Recruiter reached out to me on LinkedIn. Gave me enough material to prepare over a month and then scheduled a two-part phone interview (SQL and Python). Phone interview was pretty much exactly as everyone else explained. Just focus on easy & medium complexity problems. It is fine even if you struggle on some problem, just take the hints and communicate your though process (It is tough when you have limited time). I got the phone call from HR on the same day about the result and was invited for onsite interview. The onsite interview is like a working session with a colleague. I would say the most important skill is designing the table to get desired result followed by SQL and then python. The recruiter offered me the job 2-3 days later. You will be given enough material at each stage, just dig into that information and keep on practicing. Try to practice on whiteboard to get comfortable with the on-site interview experience. One more advice - please do not neglect SQL even if you have a good experience on it as it becomes difficult on whiteboard. Overall the best interview process i ever had. Everyone is really nice and want you to succeed.
