With 1.5 years of experience I gave interview at travel boutique online. I had 4 technical rounds and 1 final HR round. It took 2 days to complete this interview process. Had to wait for long for your interview. On 2nd day it took around 4-5 hours to complete. 1 round hardly of 30-45 minutes. Interview questions were good. If you have cleared your round then reception will say directly that you have cleared and wait for the next round else you will be asked to leave which happens everywhere.
