"Recruiter contacted, set up 1st round phone screen with a senior engineer. 45 mins with 20 mins on past projects etc diving in detial before talking about AI/LLM concepts. Was easy 2nd round was 2 stanmdard leetcode coding qns 45 mins with 1st 15 mins on behvaioural so only 30 mins to solve both qns but was quite doable. Walked though the brute force naive approach before moving on to the optimal solution and O(nlogn) etc tiome complexity."

"The process started with a recruiter screening testing some behavioral questions and some technical questions she read from a question bank. Then, I did a coding interview online. Finally, a 4 rounds loop online (as opposed to my previous attempt when I did the loop in one of their London (UK) offices): 2 coding interviews, 1 system design, 1 behavioral with an engineering manager."

"The interview process was well-structured and fairly rigorous compared to others I’ve experienced. I appreciated that the recruiter clearly communicated expectations upfront, which helped me prepare in the right direction. The technical rounds were challenging but relevant to the role, and the interviewers were professional and engaging."
