I recently interviewed with Airbnb, lyft and Instacart and they had a take home challenge as the first step. On the other hand companies like Facebook, Uber, Netflix etc. don’t have take home challenges and I was able to get to onsite. I never made to next round at Airbnb, lyft and Instacart, Curious to know what they look in the data challenge and how can I crack it! Any insights would help
I hate those tests. Doordash does that too. I downloaded the free Tableau to help cut down on time.
I hate it too specially given I’d spent solid 1-2 days over the weekend working on it.
@Call Me. how did Tableau help you do it faster? I'm not familiar with it, Thanks!
I refuse to do these free work. I hope other candidates refuses too. But I understand fresh graduates don’t have a choice. I have a PhD in applied maths and 5+ years of working in applied ML, so at this point I can say a big Fuck u to these tests. I interview candidates for ML and you really don’t need these tests if you are competent at your work.
I refused lyft and Robinhood when they asked me to take the test.
Biggest problem with these is that, if you want to impress / get the interview, you probably need to spend significantly more time on it than the recruiters tell you to
True, in reality any end to end analysis takes about at-least 2-3 weeks with multiple iterations
I agree. If recruiters mention 3-5 hours, it easily takes me over 10 hours lol. Sometimes even more.
Leetcode or take home tests LOL. it’s a choice between the devil and deep sea
Takehomes are better, at least they make you practice something useful
Is it only me who takes those tests for fun time to time??
Data scientists are expected to do a lot more consulting/storytelling in order to stand out. Did you get any feedback from them?
I agree but it depends so much on the team’s focus! Also, no feedback from any company
What am I doing wrong in my take home tests. I am spending time and energy, failing the tests and not getting any feedback. What to do :/
If you feel like you need to spend many days or multiple weeks on a takehome you’re probably not there yet. A takehome that passes interviews usually takes me only 1-2 days I also much prefer a take home for demonstrating my coding, analysis and modeling skills over a 30 min interview and live coding
It’s mainly your problem solving / hands on coding for a data science problem , not sure what they asked but I am assuming it will be some data wrangling , using pandas , data cleaning , feature engineering , feature generation , model selection , training , hyper parameter tuning and proper evaluation . Also should be able to tell a good story
It was an analytics assignment like increase engagement, revenue etc. not a lot of coding involved
you did one pf their tasks for free
