45-minute phone chat with a company recruiter, followed by a one-hour Zoom interview with an engineering team lead 2.5 weeks later. 3.5 weeks after that I endured a four-hour Zoom interview marathon with approximately nine people, including the engineering team lead (for the second time), other software engineers, a product manager, and the VP of engineering. As part of this interview marathon, I was told to prepare for a "deep dive" into a significant project I'd done in the past, so I prepared an eighteen-slide Powerpoint presentation. I felt that all of these chats and interviews went quite well, but seven weeks after my first phone chat, I was rejected with a boilerplate "not an ideal fit" email. After jumping through all of Boku's hoops and submitting to nearly six hours of interviews, I felt I was entitled to a more detailed answer, so I politely requested feedback on what detracted from my candidacy, areas I could improve upon for future interviews, etc., but I was answered with silence. Recommend steering clear of this company unless you enjoy having your time wasted. The job for which I interviewed is still posted on Glassdoor six weeks after they passed on me. They don't seem to know what they want.

It had 4 rounds. Hackrank test comprising 2 questions on graph theory and knapsack algo. Next is round to code a command line application. Then a system design round followed by behavioral fitment round. The interviewer had a very open mindset and was really flexible in terms of approach to solve design problems.
