The interview process is a bit of a joke to be honest. After initial recruiter conversation I was told that next round will be a case presentation which will be sent to me 48 hours in advance. Initially I thought the case might be something simple where it will take 2-3 hours of my time. When it arrived I was blown away by the requirements. They wanted me to develop end to end production level solution for one of the use cases which is just too relevant for their day to day. The requirements included working code whcih should generate live logs during the call. The requirements included in the requirements document itself mentioned that the case should take 8-10 hrs. Seriously are they expecting candidates to dedicate 10 hrs of their time (trust me it will take more if you are doing it diligently) - almost full 2 days worth of work just before the interview? The interviewer himself (the newly promoted director of data science) was rude and seemed disinterested during the call. I dont know whats wrong with the company but the least they could have done is be polite and actually look like you want to be there when a candidate has poured so much blood sweat and tears creating the whole project for you in 2 days. Honestly it reflects more about their culture than anything else. I wish luck to anybody who got through the process since I dont want to work for the company who is so unprofessional and just want the candidates to work for free for more than 12 hrs.
