Wissen Infotech Software Engineer Interview Experience: DSA, SQL, and graph questions

The process was short and very technical. I had two rounds. In the first, I solved two DSA problems by writing actual code and explaining my approach. I also had to dry run the solution, so intuition alone was not enough.

The final round had an ED-style format. I was asked about SQL and then worked through two more DSA questions, with graphs appearing in at least part of the problem framing. It felt difficult because they wanted more than a working answer. I had to reason clearly and keep my logic straight under pressure.

I did not get an offer. What stayed with me was that correctness, explanation, and problem structure all mattered at once. There was little room to half-solve anything.

Location: Mumbai. Overall feedback: positive. Offer status: no offer.
