I applied online. The process took 4 weeks. I interviewed at IBM (Taipei) in Apr 2015
Interview
There are three phases as a whole. The first one is phone screening. An interviewer asked me to introduce myself and get into details of my project experience. The second phase is on-site interview. They sent me a Java quiz paper and asked me to complete it in 30 minutes. The quiz wasn't hard but just some Java basic concepts. After the quiz, three interviewers comes into the room together and discussed about the previous quiz with me. Then, they asked me to do self-introduction in English, along with some questions regarding my experience. Eventually, the department manager came in and introduced the organisation to me. For the final phase, a manager from other department interviewed with me. Also doing self introduction and got some behavioural questions.
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.
