Full Data Science Mock Interview! (featuring Kylie Ying)

In this video we walk through a full-length data science interview. The task in the video is to develop a model to identify bots on a social media platform. In the video we cover topics including feature vectorization, one-hot encodings, dataset building, and more!

Thanks for interviewing me KDawg 🤠 To anyone interviewing: sometimes confidence is key and mock interviews can really help!! To anyone hiring: lmk hahahah.

[iamdan]

cheers bro! This guy has been a pivotal figure in my data science career...I started as a joke, but because to him, I believe I made the ideal choice to pursue a profession in data woow here I am today working for one the top companies here in Kenya as a data scientist

[NguyenSon-ewwn]

Hope for more mock interview videos. Thanks for great video

[nandhutp]

This mock interview definitely opened up some neural pathways in my brain. Love hate relationship continues as for as DS is concerned...Thank you both...

[chrisberdin]

Proven. Reliable. Keith Galli. I love you man!! 😂😂

[MarceloSantos-ncwq]

Keith Galli, thank you so much for that. As always a great work 🌟. I appreciate your active contribution to the data community.

[wiz]

Wow questions I never thought about though. Great Infos man🔥🔥🔥

[maggietang]

Great video, Ying is very confident and explained everything very clear

[rajesh]

Nice. That flow was quite interesting. Keep posting more interviews like this

[jacktrainer]

Dude, you carried a monitor? Guess that's the MIT difference. 😂Great video!

[leassis]

Amazing content! Really glad that you keep helping data community!

[JasonMinhas]

Great video! I have a question about the scenario. What's the purpose of implementing an ML model when the methods discussed to collect training data (X # of times reported OR reporting to engagement ratio) suffice?

In other words, wouldn't the method used in collecting training data be the method by which you determine whether an account is spam or not? If so, then what's the purpose of creating an ML model?

Sad that your channel is dying, but happy to see that your doing great!

[vectoralphaSec]

Just discovered your channel. You seem like a cool knowledgeable person on this topic. So im wondering if you can help me with a question i have. So I am a recent graduate in Computer Science and want to instead go into Data Science industry instead of the traditional Software Developer/ Software Engineer career. So as someone like me who eventually one day wants to work in data science industry, is there an entry level job role that one can apply as a starting point and just get promoted/ level up to a data science in time rather than just trying to apply for a data science position from the get go? I dont mind starting at the bottom and working my way up the ladder. If anyone else have any suggestions i would greatly appreciate it?

[robertlong]

I am a data scientist (with PhD level education and work experience) in the UK and applying to a job which would sponsor a H1B visa if successful. Does anyone have any specific advice for how to tailor my CV(resume) for this?

[gowthamkrishna]

Wonderful! Is this how the data science interview goes for fresh grad students in the industry or this mock interview is for one with some experience in ds field?

[danielsong]

Could computer science be taken to learn data science?

[aliyuprof]

Thanks a lot. I can see you both love yourselves. 😂just kidding

[paakwesiblankson]

Good work guys. You look like couples though 🥰🥰🥰

[lonnybulldozer]

Painful. Why was this in my feed? I banish you.
