Started with a recruiter phone call, very friendly person, we scheduled a coding interview later. The coding interview was very open ended and they wanted to see what kind of questions do you ask when making assumptions and then solving the question. I was invited to the on site interview later. 4 rounds 1 hour each 1) Programming Question - Very friendly person, interview was more of a collaborative problem solving. Again - they want you to assume things and want to see what and why do you assume certain things when they are not given. Cover all your edge cases - 2) Manager Interview - HR Questions about cultural fit/ Very thorough questions going to details. I think its very important for them to make sure to get a good cultural fit. 3) Data Science question - Again, lot of assumptions to be made and they want to see what questions do you ask and why you make certain assumptions. High level design question mainly. 4) System design question - I was given a very small requirement to begin with, and then gradually the complexity increased and requirements increased and assumptions were made also some number crunching involved for capacity planning. Overall I would say, very friendly people, interview is more like collaborative problem solving rather than an interrogation. Questions are open ended, for a reason. From first recruiter call it was approx. 3 weeks. I didn't have trouble getting my choice of day/date chosen for the interviews. 5 * Experience overall.
