It took 2-3 business days, I received a call from recruiter, 2nd interview was with 2 designers, it was simple, they asked about work process, 2 changes i would like to suggest for booking.com. Nice people, were very helpful.

Talked by e-mail and phone with 3 different recruiters, one was a very friendly Recruitment Coordinator who was testing my English Skills, and another 2 (in the same phone call) were technician in Front-End Dev.
