It's a huge waste of time. First, you meet with HR, then you have to complete a one-hour written test, then you meet with the department manager, and finally you have to go back to HR for a 30-minute mbti test. It takes a total of 3 hours!!!! The HR doesn't even mention the need for so many tests over the phone, wasting the interviewee's time. Furthermore, since the hr and department manager are on different floors, you need to constantly take the elevator, which is also a huge waste of time.
