I applied through a staffing agency. The process took 1+ week. I interviewed at UST (Thiruvananthapuram)
Interview
3-4 rounds of interview.
1. Appitude by recruitment team.
2. Technical interview by ust team
3. Technical by client.
4. HR round
It will be better if you have good experiance. Interviews are collaborted with training institutions in and around kerala. About 80% placement records can be found for those institutions with ust.
