I applied through university. I interviewed at Celigo (Jalandhar, Punjab) in Oct 2025
Interview
The interview process was completely virtual. There were two technical rounds and one HR round. In the technical rounds, I was asked about DSA concepts such as sorting algorithms (quick sort, merge sort, bubble sort), my academic and project experience, and core Java topics including OOP principles and debugging techniques. The HR round focused on communication and general background questions. Overall, it was a structured process but quite challenging, and I could not clear one of the technical rounds.
