I applied online. The process took 1 day. I interviewed at IBM (Calgary, AB) in Aug 2020
Interview
Lots of questions. Mainly questions coming from second-year computer science programs such as what are the principles of object-orientated language. What is a singleton? How do you write one and why you would use one. Some questions pertain to whether I read news media outlets to keep up to date on the latest technology. Some database questions such as how would I write a table based on these situation and how to write a query to obtain the inforamtion.

Question 1
What is a singleton? How do you write one? Why would you use one? What are the principles of object-orientated programming? What is abstraction?
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.
