The process took 3 days. I interviewed at Isentia (Pasig City)
Interview
Was given a test. After passing it, came back for an interview, which wasn't more than 25 minutes. Was just asked the usual questions you'd expect from HR. Got an offer the next day.
There is a grammar and summary exam where you will be tested if you suits the position. It was utmost 2 hours. After that, they will email you if you passed or not the exam.
