I won't divulge the custom questions they had because of an NDA. But I will divulge the interview questions that are carbon copy menial tasks. Of the first three phone/live-coding interviews, I was asked to do a merge sort. I guess I understand that they want to make sure I can code. But there's got to be a better problem. The many in-person interviews were (1) 1.5 hour coding-by-myself on a laptop, (2) describe a problem you worked on in detail, (3) "NLP" interview that didn't focus on NLP, instead they focused on AB testing (which is fine), (4) Lunch interview, (5) culture fit interview, (6) follow up/close/discussion interview. To be honest, I don't remember much near the end. I think I went directly home after and slept for 12 hours.
it was a bit of strings and I have write a code to output all permutations of those bit of input strings of 0 and 1
Given a DataSet they asked me to perform the analysis and email them the code
How will you improve yourself in this rapidly changing field?
After one hour face to face interview with couple of tech leads I was assigned a skill test to complete by the HR team. The skill test focuses on (i) SQL skill and coding (ii) data modelling skills and coding. The supplied data is their own dataset so any solutions you suggest are straightaway useful for them. The promise was once the results and code are submitted the chief scientist will do a technical assessment of the method and or results through an interview.
Tell me about a time when getting stakeholder buy-in was difficult but critical for project success.
Gave a Case study to solve using LSTM and 10 days to solve it. After they reviewed the solution, I was called back for another round, and a deep dive on the approach and process was done. Some technical questions on working of LSTM Gates, and the data pre processing approach was tested
The Technical interview revolved around NLP and CV problems. For the assignment, there were two questions. Build an API for image similarity and build an API to tag product titles with different attributes. The tagging problem also had a set of titles to be tagged and sent back. The time limit was 2 days.
