I interviewed at IBM for a software engineering role.

The process began with an online assessment, covering cognitive ability, coding, and situational judgment.

This was followed by a technical interview, where I solved coding problems and discussed my experience with college projects.

A behavioral interview focused on teamwork and problem-solving, using the STAR method.

The managerial round assessed leadership and career goals.

Finally, the HR interview ensured a cultural fit and clarified work authorization.

I received an offer shortly after, reflecting a thorough but fair evaluation process.
