I applied online. The process took 5 days. I interviewed at IBM (Singapore) in Mar 2014
Interview
I found their job post in a Job Board (glassdoor.com) and applied to their site directly. Few days later or a week after they called me and invited me for an interview. I was not informed of the written exam.
Interview questions [1]
Question 1
There were lots of coding items in the written test for 1 hr. First part is multiple choice. About Java threading and memory management. Second part is the coding. Most items are using arraylist. I was not able to finish the exam so during the interview they asked me how did I arrived with my answers. I felt I was able to answer them well or convinced them with my answers but I was wrong to assume on that.
I made a follow up if I passed. Unfortunately, I receive the confirmation that they will not proceed further with my application.
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.
