I applied through university. The process took 2 days. I interviewed at IBM (Singapore)
Interview
3 rounds of interview - one written test followed by a one on one interview with an existing full time employee. This is then concluded by an onsite interview with a panel of interviewers. Interviews were technical with the exception of the group were a few general questions were asked. Hiring was a simple phone call and email followed by a one day on-boarding process which took care of legal details and company pollicies.

Question 1
The most difficult question started of with a recursion of the fibonacci series. Then it progressed into obtaining algorithms that fit a use case eg. create a recursion that generates this subset of the sequence represented by a binary tree but has to execute in (n*logn)
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.
