I applied online. I interviewed at IBM (Dublin, Dublin) in Sept 2021
Interview
Technical interview - 1st round
Asked me to explain every bullet point from my resume along with how I used all the technologies mentioned. Further questions were from DevOps, Docker, Kubernetes, Spring, 3-4 code debug questions, JVM, GC.
The irritating thing was that the interviewer was writing every word to word that I was answering. I had to repeat every answer multiple times to get him to write it.
Was scheduled for 60min but went on for over 90+min.

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.
