An easy coding exercise at the beginning followed by a bunch of mostly theoretical questions from the programming language, frameworks, databases, concepts like microservices. Unfortunately the interviewer was from another project and couldn't answer my questions about the role.

Application

I applied through a recruiter. I interviewed at Luxoft (Toronto, ON) in May 2026

Interview

The interview was for a contract role opportunity. It consisted of 3 rounds, one technical screening (45 mins), one managerial (30 mins) and one client round onsite (45 mins). Questions were based on Java, Python, SQL, Design Patterns, Microservices, AWS and one coding question. I cleared all the rounds but didn't get selected because of tough competition between me and the other candidate. The screening interviewer was quite friendly and tried to greet me in my language. The interviewers for client round were also friendly throughout the process and also dropped me back to the elevator area.
