I was reached out to my a recruiter and asked to take a fairly easy HackerRank assessment, passed that. Then I was assigned three interviews with the members of the team. Although due to a scheduling error on their part I only attended two of them. At these interviews I got asked a LeetCode medium question and a LeetCode hard level question. Maybe I just got unlucky, but the difficulty of the HackerRank questions (which were really easy) did not line up with the level of questions I was asked during the interview.
Interview questions [1]
Question 1
LC M: Make the smallest number by removing k
LC Hard level: Still cannot find this question or even how to solve it, but it involved recursive backtracking and I was stumped.
3 Rounds.
(INTERVIEW IS HELD IN ENGLISH)
1st Round: Screening, talk about your cv, study enough to have mastery over the subjects your projects cover. Investigate company values, why you want to join.
2nd Round: 60 min technical live coding interview. Depending on position it ranges from a leetcode medium to a hard.
3rd Round: Didnt get thru, Ive heard its a intro systems design interview.
Interview questions [1]
Question 1
Leetcode medium, string manipulation type of question.
Technical interviews, they ask coding and algorithmic problems, there is also a soft skills section with STAR like questions. Results come back fast, which I think was nice. Usually there are three rounds of interviews
I applied online. The process took 4 weeks. I interviewed at C3 AI (Guadalajara, Jalisco) in Apr 2025
