Jarvis Consulting Group Software Developer interview questions

The interview was actually very, very easy. They asked some basic SQL concepts like joins, foreign keys and primary keys, a few questions regarding data structures and algorithms etc. I received an offer right after the interview.

I can't remember anything because the interview was a couple of months ago. but questions related to SQL language, indexing, algorithms, and data structures and also online coding about he data structures. the difficulty was average and I passed all three interviews but finally they didn't contracted with me
