There are 5 rounds interview in total. First is a mental math test in Singapore office supervised by a HR. The question involves three classes, you need to finish 75 problems within 10 minutes. Followed by a personality and IQ test. The HR said about 60% candidates failed in the these tests. Then I came to the office and had a talk with HR. I doubted that HR Representative did not even look through my resume since the HR I used to contact was on leaving. And then I received a rejection letter. The processing speed was really fast. And the singapore office would look for candidates in India University. And it is said that more than 500 people applied position in one india university.
