Hard Hackerrank. Questions on Dynamic Programming, Backtracking and Bit Manipulation. Very DSA focused. Requires intense Leetcode preparation. Doing competitive programming on platforms like CodeChef and Codeforces would definitely help. Overall, a hard interview.

Phone screen, probability and algorithms questions. They were all very easy questions. While I could solve them, I was too slow, which is probably why I did not get an on-site invite.

Talked with the recruiter but was noticed the following week that did not get a technical interview. Went over the resume and the process was smooth so seems strange that did not move forward.

The whole process doesn’t take much time. The first round is OA. The second round is phone interview. It includes one Markov chains problem and one coding problem. The last round takes one day. But the manager interviewer is not content with my performance. So the last round stops earlier. The final round takes up to 6 interviewer and each round includes coding problem.

Interview Questions
  • A and B toss a fair coin. A - HTH, B - HTT. Any three-sequence has a match of A/B patterns, we have a winner. P(A=winner) = ? (Sol: Markov Chains)

I applied through an employee referral The process took 3 weeks. I interviewed at Citadel (London, England, England) in Apr 2021

Interview

I applied via friend's referral on Mar 15th. Interviewer scheduled an intro call on 23rd march. They explained to me the NXT enterprise position and the interview process. They skipped the hackerrank [coding] round. So my first round was virtual interview with 2 interviewers [1hr each] - 1 technical coding; other behavioral. It was scheduled on Apr 7 and was told I'd get a feedback in 1 day. But I got a reject on Apr 12 [couple days were weekend].
