I applied online. The process took 4 weeks. I interviewed at IBM
Interview
Applied externally through Linkedin/Glassdoor
Received a coding challenge that comprised of 3 questions (time limit 3hrs)
First involved basic API calls, second was a DP question, and third was about implementing functions in React given some boilerplate code. Definitely needed the 3 hours for polishing up the last question.
A week later, I was notified that I am moving on.
Online interview consisted of technical Javascript questions and general inquiries about background/resume.
After this step, there was no communication for about 3 weeks, so I assumed I did not get it.
Got a phone call, about a month after my online interview saying I got an offer.
Interview questions [1]
Question 1
What is a promise in Javascript and could you give me an example of when using promises can be ineffective/inefficient?
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.
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.

## 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**.
