I applied online. The process took 2 weeks. I interviewed at IBM (Dublín, Dublín) in Oct 2024
Interview
I was given a HackerRank coding assessment, which included 2 questions (ranging from normal to hard) related to data structures and algorithms, and I had to complete it within 1 hour. Both questions were clear, and it followed the standard HackerRank setup, allowing me to use any programming language I preferred with no restrictions

Question 1
A range, such as 1-200, was given, and the code needed to return numbers that have two identical digits, like 100, which has two 0's.
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.
