I applied online. The process took 1 week. I interviewed at IBM (New York, NY) in Nov 2016
Interview
I applied online through their website. The next day an email was sent out requesting that I complete an IPAT test that is linked to continue to the next stage.
The test is timed where you have to complete a series of cognitive questions before the time runs out. There are plenty of resources describing it if googled, but it can be likened to an IQ test with reasoning, ratios, number sequences, etc.
The test was to be completed within 7 days, but recommends completion within 2 days. A response by email is usually within a couple of days.

Question 1
Number Sequences, Verbal Reasoning, Ratios/Geometry
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.
