EXL Service Software Developer interview questions

This was my first round which was technical, mostly focused on spring boot related . interviewer ask some prefix question and 1 mutithreading question on compiler. i was not able to clear inteview

It was 2 round online interview. Both were technical round focused mainly on python and medium level DSA question. Second round was purely on python and Machine Learning, data science. Overall interview was medium difficult as it was on campus interview won't know about off campus much. I was very confident about python and DSA so I cleared all the rounds and got an offer.
