Infosys Specialist Power Programmer interview questions

When I applied then after almost 2 months I got call, then scheduling the interview first round took another 1 month. After that when I appeared for Coding question same day technical interview happened. The HR guy was very weird and rude, as well as the interview person. After that 1 week later they asked for documents. Then after that another 1 week the TA person called and offered. But I had already joined somewhere else. The TA person was not really interested and was giving me weird conditions for joining because my current CTC was greater than the offer. I said I could have joined if you guys had faster process.

Difficult interview. 1 codeing question. And rest all based on technical stuffs. Overall you should know Data structure and algorithms well. They will ask questions in based on backtracking trees
