I applied online. The process took 6 weeks. I interviewed at Rokt (New York, NY) in Jun 2022
Interview
My first interaction was a take home coding assignment. It was interesting and fun, but it took me a bit of time to complete.
The next round was two technical interviews: one coding, one system design. These were relatively straightforward, and I had a good time chatting with the engineers after.
One round with CTO which was also great to get to know his style and more about the company and culture.
They asked me to complete the cognitive test after I had passed with that round. I think I was supposed to at an earlier stage, but it didn't happen until later for some reason.
Last was a bar-raiser which was a chat with a non-technical executive. This was filled with a lot of ambiguous questions and I considered the toughest round. But I also learned more about other departments within the company and how they operate.
Overall, the process took about 1.5 months.
Standard IQ testing + 2min video about project I'd completed, then zoom code interview, then system architecture interview, then finally a fit interview. Early interview section was fairly easy, System design was a pretty reasonable 2 stage login/verification app, fit interview was quite engaging and in depth.
Interview questions [1]
Question 1
System design was a pretty reasonable 2 stage login/verification app - was asked first to design a scraper to import logins from a text doc on s3 to a db. then infrastructure on how to get logins within 100ms from front to back.
Was in invited to a virtual coding interview as the first round, was equivalent to an easy leetcode problem. Did not finish question within the interview because I got tripped up, but the interviewer said he saw that I had the solution. Got a rejection email a week later.
Questions similar to IQ tests for an initial round. Coding interview was online with live interaction from the interviewer to talk through the thought process. System design interview was quite involved. It really focused on the thought process and design reasoning rather than knowledge, with the interviewer accommodating any knowledge gaps I had. Behavioral interview was fairly standard.
Overall it felt they made an effort to make the interviews fit the candidates' experience and expertise, which I appreciate.

Question 1
Leet code style, roughly medium level coding question.
