I applied online. The process took 4 weeks. I interviewed at IBM in Jan 2017
Interview
Sent a 3-4 hour coding test which you can do from home alone, if successful will schedule a technical "in person" interview online. This is where you will be asked classic algorithm/ data structure questions. If successful then you will do a 1 hour behavioural interview which is more of a conversation just to get to know you and your goals
Interview questions [1]
Question 1
is a string a palindrome?
Given a unsorted array of numbers 1-100 find the missing number, what is the run time of your algorithm?
A brain teaser
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.
