What a waste of time!! I mean I have interviewed at my share of companies but this has to be the worst. Please note I am not saying toughest but worst. What made it even horrible is all their blog bragging and telling you that it's going to be a "Pair Programming". I wouldn't even mind the complexity if they wouldn't have advertised by saying there's going to be a "Real Life" questions. At least I could have prepared for 5th standard puzzles.
Inital take home, followed by extension interview, followed by a coding challenge, followed by system design interview.
The whole process took 3 months!
The interviewers are usually really nice and want you to do your best.
The interviewer was nice, and he is friendly and willing to give hint, the question has 2 follow-ups, it was hard to complete in time. The question was not a typical LeetCode
Phone screen and then a full day of interviews. 3 pair programming challenges, a system design review and a prior experience interview. There was also an onsite lunch with a person from the company.
Interview questions [1]
Question 1
To design a hotel booking system. Pick any part (backend, frontend, database, api etc) and deepdive into that, explaining the decisions along the way.
