You received feedback 2-4 days after each round, and the process was clear about what each new round entailed. This whole process took about two months, which was quite long compared to other interview processes at different companies.

IQ test - Basic maths, vocabulary, and pattern recognition. Hackerrank test - 4 questions, ranging from easy to hard. I didn't get 100% on every question, but they said I did well. Recruiter call - Asks about interests. I stated I was interested in the ML team. CS interview - Pair coding for string comparison. Questions about CS fundamentals. CS interview part 2 - Asked about previous experience, and how I would solve a practical problem. Bar raiser - This is like a behavioral interview. A non-technical VP asks about collaboration and leadership skills, and why they should hire you. For me, this was the hardest round. Starting with an IQ test makes for an off-putting first impression, but the rest of the interview is pertinent to job skills.
