IBI Group Software Developer interview questions

It was based on data structures and algorithms, And based on projects. There were 3 rounds out of which last one is hr round, remaining are based on dsa and projects,

I got an initial phone screen with basic questions about your background. HR was very kind and personable. Immediatelly set up an interview The interview had around 40 rapid-fire terms and definitions questions, which probably depends on your resume. Then some characteristic questions, and questions about your previous positions. Felt like it went well, and the panel said that they would be in contact within the week. After a week I reached and said they had not reached a decision, another week passed, and still silence so I assumed that I was rejected. Not sure why companies don't have the courtesy to just give you rejection at least.
