Based on my performance in CodeVita. I got a direct interview with TCS. Interview panel consisted of 3 members. TR, HR and MR rounds we're clubbed together. Starting questions were like general HR questions then after sometime based on the skills mentioned in resume technical questions we're asked. Questions will also be asked from core subjects ( non CS/IT branch can expect questions from there core subjects). Further questions were based on problems solved in Codevita (it is expected from interviewee to write whole code). Also questions based on latest technologies were asked. My interview was for about 20 minutes. Note: Each panel had unique way of interviewing. There were approx 30 panels and in some panels nothing was asked about code submitted in Codevita. Further questions were posed based on branch (CS/IT/EC...) and interview duration depends on the panel some were 10-15 minutes while other had interview for more than 90 minutes
