Intel Corporation interview questions

An 20-minute call with manager, followed up by a 90-minute technical interview with two software engineers. The interview itself was smooth. But the timeline wasn't. I had to wait for two weeks after the final interview while holding another offer, written two letters following up on the final result, only to get rejected.

They mostly ask about dsa and subject related questions and answer. Moreover, they asked to explain about project. Some of my friends tells to me they just go through resume and asked questions from resume topics.
