Sikka Software interview questions

The hiring team provided me with a take home assessment (to build end to end AI solution), it wasnt easy, invested 5 days (day in and out) straight in designing and writing code. The provided solution was pretty elaborate, they called for interview. I answered all their questions. I dont know what they are expecting from candidates, even though i answered all their questions, solved the coding questions successfully, they still rejected me and did not even bother informing me about it. It is very unprofessional of them to not respect my time, i spend 2 weeks in this process, they didnt even provide feedback. Their loss!

The interview process included three rounds: one with an associate HR, a technical round, and a final interview with the CEO. The entire process was efficient, with quick decision-making. Tech round was a take home assessment.
