  • All right, so some of you might know that I just quit my data science job at bank

  • the reason why I'm not seeing explicitly which company

  • It's in case I need to go begging back for my job, you know, and I don't want them to say that

  • Oh my god, what did you say this about a company?

  • We're not gonna take you back now before I go into why I quit my job

  • I kind of have to re-explain what my role was as a data scientist

  • and the reason why I have to react splain it is because

  • It's not as standardized as like software engineering which is I mean III know I explained in a lot of videos

  • but I'm just gonna do it again just so that you can have

  • the right context to understand why I quit so basically

  • this was my job title at this company and

  • Yeah, so you can read it

  • so in essence in my words

  • A data scientist is usually put into a product team and usually in the product team. There's a product manager

  • there are software engineers and there's a data scientist now, obviously there are other roles, you know, for example like UX researchers and

  • Like product specialists

  • Marketing people legal people and stuff like that, but I'm just gonna you know, simplify it and say ok

  • So there's software engineers and data scientists and product managers

  • So I'm not gonna explain it in a way where it's like, oh data scientists. They make models

  • They use like R and likes are for engineers, they build infrastructure and they use programming languages blah blah blah

  • I'm not gonna explain like that

  • I'm gonna explain it in a more fundamental way of what their roles actually are. So

  • Engineers they actually have the technical abilities to build the thing. We actually want to build product managers

  • They're basically the leaders are like the owners of the product. They decide what the product is going to do

  • And also what the product should be doing. Basically they have the vision and they're in charge of actually executing getting the shit done and

  • You know, they'll do whatever they need to do to actually ship a product in some ways

  • You could think of them as like mini CEOs of a product or a feature and then data scientists

  • we have the most time to think because we

  • Don't need to like build anything like for engineers and stuff like that

  • And we also don't need to focus on execute and talking to cross-functional partners all the time

  • So in some ways because we're able to think more than those two counterparts

  • We're basically like advisors are like consultants of like the product. We don't actually make the final decisions and calls

  • I mean obviously your opinions matter

  • but in in essence the the people who had the final say are kind of the product managers and also the engineers because

  • The engineers are going to build it so they could build whatever they want and then product managers

  • They're the ones

  • They're the ones that decide on the future of the product now because we have so much time to think our job is

  • To try to understand the product inside and out. We're suppose

  • Not I'm not saying all data scientists do that

  • but I think

  • That the fundamental role of a data scientist is to understand the product in and out better than anyone else

  • The reason is because like I said, you have more time to think you have more time in your hand

  • So basically we use data to try to understand exactly

  • what the product needs and where the product should go in terms of the product direction and

  • What we can do is we can tell our team exactly where we should prioritize and how we should do certain things

  • Why because we have so much time to think about it, you know, we don't need to build stuff

  • We don't need to execute on anything. So that's a role

  • We're always making sure that the team is working on the most important things

  • Currently, okay, I'll do one more analogy just because I like doing analogies. So imagine a youtube channel, right?

  • Engineers would be like video producers which is the people who actually know how to make videos because in the end if you don't have

  • A video you're not gonna have a video channel

  • so I think of Engineers like video producers and then product managers, I think of product managers as

  • The people who?

  • What it doesn't need to be multiple people

  • it could just be one person but basically the person who sends emails tries to look for sponsorships and

  • They think about okay, where should this channel go? Basically they do everything that's not related to videos

  • You know, we got Brandon we got sending emails making websites communicating with other youtubers. Basically just all the crap that

  • Video producers might not want to do so

  • I think those people are like the product and then we got a data science

  • The data scientists would be kind of like an an analyst of your YouTube channel

  • What analysis would do is they would all they always look at analytics to make sure that?

  • You know you get some insights to know what kind of videos to make next like for example

  • You look at the views and they say that okay

  • You know these things are kind of hot right now or this is kind of trending

  • And you look at comments - basically

  • You're like you're trying to understand your users the best way you can using data or anything. Actually, it doesn't even matter

  • It doesn't even need to be data. So basically

  • those are the fundamental rows basically a data scientist should figure out you know how to get more subscribers how to get more views and

  • Why are certain things working or are certain things not working?

  • So then give them insights give the product manager or like the video producer insights into like okay, which you make next

  • How should we you know like these strategies? Okay. I know that was kind of long just to explain

  • fundamentally, what a data scientist is

  • Fuck I need water

  • Okay, I'm too lazy to get water okay, but um basically the reason why I quit my data science job in essence

  • It's because I'm still exploring

  • so I guess what I'm trying to say is a lot of people are content with their first job out of college and

  • For my case. I think that

  • For the first years out of your college

  • It is totally okay to keep searching and try to understand yourself and try to understand what exactly

  • Is a right fit for your in terms of a job like I prioritize well, I might be wrong

  • I don't know but I prioritize long term like for example, if

  • you know, I just stuck of data scientists and

  • In the future. I realize I hate the job

  • then the cost of switching jobs is a lot higher later on if I was already five years or six years in so I do

  • think that sacrificing the first few years

  • Trying to discover what you actually want

  • It's definitely beneficial for your career. Hopefully, I don't know

  • We'll see so I'm not saying oh by the way, I'm switching to software engineering

  • I have a feeling that some people don't know but I'm not saying that software engineering is my

  • True calling or that this is the final job that I want. I don't know. I'm not sure I might be wrong

  • You know, I might not even last for like another year or two

  • But in the current state that I am right now

  • I feel that I don't want to do you know the analytics part like, you know?

  • The YouTube guy where he just looks at analytics. I kind of want to make videos

  • I want to be a video producer

  • So in this analogy, it means that I want to build things and I think that's currently what I want

  • at least what I think I want so that's why I'm gonna try out a software engineering now and

  • Yeah, cuz I thought that I was always a builder, you know, I do like some aspects of data scientists

  • But you know, I want to try to build stuff this time like I think at the core

  • My personality does fit more of a builder, you know, I do like building stuff. But yeah, so yeah

  • So those are the arguments of me wanting to become a software engineer

  • So I'm gonna talk about some things about why I don't want to be a data scientist anymore

  • So at least at my company or my old company the way you get

  • Evaluated no matter what role you have is how much impact you have?

  • And basically what impact means is if you did you have like a positive contribution to the company

  • So even if you worked your ass off or you did, you know, you do a lot of smart intelligent things

  • But it doesn't have any positive impact to a company or like it doesn't really change anything

  • Then you still might get fired after a while. So as a data scientist using the scope that I talked about like the fundamental ROS

  • basically

  • how a data scientist can have impact in a company like that is by

  • Make like being like influencing the product. This is

  • influencing the product direction

  • so for a data scientist using that scope of like fundamental ROS a

  • Data scientists how they can have impact is by you know

  • Making analysis or something such that it leads into

  • actionable

  • Insight meaning that people will use that insight and then they'll take action to towards it and then it will benefit the company

  • So that's impact. All right, so I have a few examples. I'm just gonna read it out loud because I I can't remember them

  • So basically in a simple way if your analysis convey the engineers to build something and our metrics went up

  • That's impact

  • Also, if your analysis convinced the PM and the team to put a new feature a or a project on the roadmap

  • That's impact

  • If you create an amazing

  • Prediction algorithm to predict whether a user watched a video with alone in their apartment or with friends

  • But the team didn't decide to implement it because they don't think it's useful that is not impact

  • if you found that Korea is a growing market for live videos and you have tons of evidence that

  • Adding a donation button can make your company dominant in the live video market in in Korea

  • But even with their sound evidence you cannot convince your product team to focus on Korea. That is not impact

  • So as you can see

  • it's not always a hundred percent fair because for some team it might be easier than another and

  • There's a lot of factor that plays into the success of a data scientist and some of them are out of your control

  • And that was one thing that I found a little bit harder to cope with

  • Now I've worked with teams where it was really really easy to find opportunities and then you show those

  • Opportunities to them and then they're super excited and they'll do it, you know, and that's a lot of impact

  • but I've also worked for teams that

  • Move a lot

  • slower against a more friction and basically, you know

  • you don't have as much credibility to them and

  • And it's a lot more difficult to convince them to do what you want to do. So that's why it's a little bit harder

  • So and basically if you have no influence, you don't have impact as a data scientist now

  • Sometimes you might be lucky that your work is so good that your work speaks for itself, right?

  • But the reality is that in life that's not always the case. Sometimes you just have to be influential

  • Basically, you have to have the skills to influence your peers let your engineering manager the product manager

  • you have to get them in the same team as you or you have to basically or

  • Basically, you have to kind of convince them that your ideas are good and that they should implement it. But that's the thing

  • It doesn't always happen and sometimes you gotta be pretty good at like the office politics or like

  • you know stuff that or more like soft skills ish and

  • I believe those were the skills I lacked or at least that's why I thought before and which made me kind of like yeah

  • Like believe it or not. I'm actually

  • kind of like a work introvert so

  • I'm also like still very inexperienced in in in understanding like the work

  • Dynamics and also like some office politics and stuff like that

  • I'm still quite new. So I mean I did get better but at the time

  • that was what made me want to switch to software engineering because I felt like I wasn't ready to be a product leader on my

  • Team, I didn't feel like I had the maturity to make and influence decisions on my team

  • I didn't have the confidence in myself nor my work and that

  • Stressed me out. Yeah, that stressed me out now. Don't get me wrong

  • there's a lot of

  • aspects of data science that I

  • Enjoy and that I like and that I still like and I do hope that when I work as a suite that I could use

  • some of the things that I've learned and

  • and use it as my advantage but basically how I think about it like my philosophy is that your goal should be like

  • Oh, I should be really I should be a really good data scientist, or I should be a really good software engineer

  • You should be the ultimate worker

  • Okay, that sounds kind of weird

  • But basically what I'm trying to say is you want to be the guy who can solve everything with anything, right?

  • Like if there's a problem

  • You're the guide to solve it

  • No matter if it's a technical problem a business problem or like analytics problem and stuff like that

  • you want to be the guy that people can depend on and that's the person that I'm trying to be and

  • For now the skills. I want to work on or you know building skills like a software engineer

  • So yeah, I mean, I haven't done that in ages. I kind of miss it. Okay

  • So now what you know, what am I doing now? Well, I am unemployed

  • So basically what I do is every day, I just sit on my ass and I work on interview problems

  • I do a couple of questions on alcoholics per die. Oh just so that I can refresh my memory on these coding interviews. Yeah

  • It's a good website. I highly recommend it

  • Yeah, you should check it out. If you're if you're interviewing also, what else have I been doing?

  • Yeah, so, you know because I have so much time in my hand

  • I've been going to blind a lot blind. Is this like Anonymous?

  • Forum app that you can check you could check like gossip

  • so basically when I worked at like my company X

  • what I could have done is I could have gone to

  • Blind and see what other people were talking about that also worked at company X so a basic a lots of gossip

  • But I also use it for non gossip and there's a lot of stuff that you can read about in like normal topics

  • We're just a bunch of people from Silicon Valley

  • They just talk about random stuff and most of the time to talk about, you know

  • switching company

  • interviewing at your TCC

  • Total compensation how much they make it's a good way for me to get a feel of what the market is like right now

  • So I use it a lot

  • Almost obsessively a lot of times I check like okay, you know

  • You know company X interview process to kind of get a feel of like how they interview you. So that's what I do

  • I mean you guys should totally check it out. It's pretty cool

  • You know lots of lots of anonymous talks there

  • yeah, so basically, um, you know, I mean I get a lot of questions sometimes from people saying like oh,

  • How should I do X or where what should I do to find X Y or whatever. Oh wait, my camera's almost on

  • Yeah, so pretty much like I get a lot of questions where sometimes I don't even know the answer

  • But how do I get the answers, you know, I go to Google I go to you know algo expert to learn some stuff

  • I use blind to understand how the interview process or like I use a lot of these websites

  • So I feel like you know instead of me answering all the questions for you guys

  • I should just give you the tools to answer these questions, right? So there's this quote. You know what they say

  • Give a man a fish and you feed him for a day

  • Teach a man how to use blind and they will get into a career and buy organic fish from Whole Foods

  • for a lifetime

  • Alright, that's all I have to say for today. Thanks for watching

  • peace

  • Forgot that feeling the Sun in my face, it's our well needed

All right, so some of you might know that I just quit my data science job at bank
