I recently participated in the Infosys interview process through HackWithInfy and got selected for the next round in Category 1. The onsite interview took place at the Infosys office in Sector-62, Noida.
Round Structure:
Online Coding Round (HackWithInfy):
I received three coding questions and performed well enough to qualify for Category 1.
Onsite Coding Round (45 minutes):
At the Noida campus, I was given one coding problem to solve on their platform.
One of the problems was related to Binary Trees, and another involved Graphs.
I tried the graph problem, but only a few test cases passed.
Technical Interview:
After the coding round, the interviewer asked several DSA questions, including topics from trees, graphs, DP, and problem-solving.
SQL questions were fairly straightforward.
They also asked about my projects and resume.
I struggled a bit with the DSA part — while my intuition was correct, I couldn’t articulate the exact solutions clearly under pressure.
Overall Impression:
The interview was fair, and the questions were a good mix of coding, theoretical concepts, and project discussion. However, it was challenging, especially the DSA part, and requires strong clarity in algorithms.
Advice for Future Candidates:
Prepare well for core DSA topics, especially graphs, trees, and DP. Practice writing clean, efficient solutions under time constraints.
