I applied through a recruiter. The process took 1 week. I interviewed at IBM (Shanghai, Shanghai) in Jan 2016
Interview
I joined the IBM Global Delivery Company Limited weeks ago. Our team worked for the Suncorp project. It is a Australian Insurance company. There are three rounds of technical interviews, all are phone interviews because they won't reimburse the cost of travelling to Shanghai. First round is quite simple, just some basic questions on Java and English skills. In second round, two engineers interviewed me, they started with simple questions and then go deeper. I really enjoyed the process because they asked some awesome questions and they did it not like an interview but like a technical discussion, the atmosphere is comforting. Last round was from another team, this interviewer behaved a little more serious, all discussion are all technical oriented.
what do you know about java concurrent package, what is the difference between concurrent package and synchronized classes. I mentioned concurrenthashmap, they asked how it was implemented. Luckily I read the implemented before so I gave a briefing of its code design details.
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.
