I applied online. I interviewed at Affirm (Montreal, QC) in Aug 2025
Interview
It was a technical interview that included a question and a follow-up. The question is very similar to Leetcode 380 (Insert Delete GetRandom O(1)), but a little more complicated and involves the use of a Java hashmap or Python dictionary. The interviewer was very kind and helpful throughout the interview. I passed this interview but the position was taken by someone else before my second interview.

Question 1
Very similar to Leetcode 380 Insert Delete GetRandom O(1)
Took roughly 2 months total. Recruiter was very fast to respond and the interviewers were all very nice and collaborative during the interview. Typical HR call, two technical rounds, and behavorial round.
Live coding #1 focuses on algorithms and data structures, testing problem-solving skills and efficiency. Live coding #2 emphasizes coding challenges and practical problem-solving. The behavioral round assesses experience, teamwork, and culture fit.

They asked a coding problem on arrays and hashing to test problem-solving and algorithmic skills.
There were three interviews: one with HR, and two technical ones. Quick process, the recruiter was very responsive. Leetcode style questions in the technical interviews, the first one was easy while the second one was medium/hard.
