I interview at IBM Canada, Markham.
The process was pretty much strict forward. The interview comes with a HR interview, then a hiring manager round, a Online Assessment(HackerRank) and followed by a coding round(HackerRank Live)with a bunch of theoretical questions.

## IBM Interview Process
The process began with initial resume shortlisting, followed by competitive **DSA and coding rounds** to test core technical concepts. After clearing those, I cleared two comprehensive interviews with the **Hiring Manager/Tech Expert** and **HR**.
Describe the interview process: The process consisted of three rounds: an initial online assessment focusing on data structures and algorithms, followed by two technical video interviews. The technical rounds were intensive, covering system design, live coding, and deep-dive questions into previous project experience and database optimization.
