I applied through college or university. The process took 2 weeks. I interviewed at IBM (Littleton, MA) in Apr 2016
Interview
I had two phone screenings which lasted about 30 minutes each. We talked about my relevant experience in classes and previous internships.
After the two phone interviews, I was called onsite. Overall, the experience was smooth and they communicated well.
Interview questions [1]
Question 1
Since I was applying for a team whose work pertained to incorporating machine learning into their services, questions I was asked had to do with training and evaluation of learning models, e.g. what metrics would you use to compare the performance of two classifiers and why?
Things of that nature.
There was also timed online assessment I had to take, which contained logic and arithmetic problems.
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.
