1st round is system test no matter how much experience you have, if you not cleared that's it, they keep it in business hours and waste time of candidates,Please keep face to face interview then only you can judge the candidate well my half day got wasted.

We had on online test consisting of aptitude, technical and 2 coding questions for 1hr 20mins. Coding questions was slightly difficult and given time was 30mins. They shortlisted 30 students. The next day we had technical interview and from that 7 students were shortlisted. The shortlisted students were called to their office and had hr+technical interview. Only 2 students got selected from that.
