Codewalla interview questions

first round 45 MCQ base question test which is in 45 minutes online mode then offline Technical interview and HR interview at company office and finally offer letter allocated base on overall performance .

The interview process consists of 4 rounds. 2 technical , 1 techno managerial and HR round. The process took almost 15 days as the HR was not proving the feedbacks on time. Even after clearing all the rounds, they declined to give me offer stating some irrelevant reasons.
