I applied online. The process took 3 months. I interviewed at IBM (Toronto, ON) in Mar 2017
Interview
The whole process is super super slow, took around 3 months. First, 4 hours coding assessment. Second, half hour asking something about resume and two simple coding questions: fizz buzz and move all the zero to the end of the array. Third, one-hour coding questions: check winner of the tic tac toe and design a deck of a poker. Did not made it to on-site interview. Overall, it's very easy, but I don't know why I did not make it to on-site.

Question 1
check the winner of tic tac toe, design a deck of poker (draw and shuffle)
fizz buzz, move zeros
Applied through the company portal, completed an online coding assessment, followed by a technical interview covering data structures, algorithms, OOP concepts, and project experience. Concluded with an HR discussion about the role, career goals, availability, and compensation expectations.
## 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.
