AspenTech Software Engineer interviews, decoded.

I applied for the job opening through the college campus website. I interviewed with 4 people, one by one, and then had a final chat with HR. It was the typical process: first meeting a coworker, then meeting the managers/leads. I got an offer about 3 days later, but they only gave me one day to accept because it was near the end of their fiscal year and they needed to hit their targets. They wouldn't extend the deadline.

Got an email for a phone interview, which was pretty straightforward, mostly covering resume details and fundamental OOP. The onsite was a week later, involving four interviews: two technical, one with the manager, and one with HR. They suggested preparing C++, OOP, basic algorithms, and data structures like linked lists and hash tables.

I had Algo and DS questions using the language of my choice for different positions, so it was varied. Also, I had a call to meet the rest of the team and another call for the technical assessment. They were very polite.
