I was contacted by a recruiter for the position of Senior AI Engineer at Target.

I had a 30-minute chat with the recruiter regarding my prior work experience and interests. This was followed by a 45-minute technical phone screen. One of the senior engineers called me and posed coding questions on a code interview platform.

I was selected for final interviews, which were conducted a week later. The interviews were done on Zoom and consisted of four rounds, with a 15-minute gap after each round.

• The first round was with a Lead AI Engineer. They asked me questions on a code interview platform, starting with a simple ML problem, followed by SQL and a coding question (first non-repeating character in a string).
• The second round was with the Principal AI Engineer of the team. They asked me questions regarding my work experience and projects, and conceptual questions about REST APIs.
• The third round was with the Director of the team. She was very cheerful and asked me mostly behavioral questions. I enjoyed talking to her!
• The fourth round was again with a Lead AI Engineer. They asked me about my projects and some SQL questions on a code interview platform as well.

Overall, the interview process was great, and I got to talk to 5 out of 9 members on the team at Target.

October 9th: I received a rejection stating they were going ahead with another candidate.

The question was simple: return true if a sum k exists in an array, else false.
