I went for the interview of this position twice on two separate occasions but I'm just going to describe one of them.
This happened a few years back, at that time it was a combined role.
I had to sit for a translation and customer service test, but majority of the focus was on the translation. I was told my translation was not "flowery" enough, hence the reason why I was rejected on the spot, despite the fact that I satisfied 95% of the requirements based on their job advertisement.
More details on the test: there was no background information on the customer service questions. They throw you a lot of questions which involved real-life game issues. Unless you have actually played ALL of the IGG games and know all the bugs the games have, you wouldn't even have a clue to how to respond to those issues. You can provide a brief format, but I have no idea what kind of answers they were expecting. And I'm commenting on this as someone who did a year of customer support for a mobile game my ex-company had - you need to know the game through and through to be able to handle all those customer queries.
My salary expectation was also too high, and the highest they could offer me was 1.8k for all the 3-in-1 role (SERIOUSLY?). But according to Jobstreet, their stated salary was "around my expected salary". 1.8k was not even close!
The interview was pretty standard. No tough questions asked. However, one thing to note is that, even though the job advertisement clearly stated that "fresh / inexperienced candidates are encouraged to apply" they were looking for a candidate with real-life work experience in digital marketing through social media. This was for the "production" part of the role. And they were clearly also looking for native Chinese speakers. Perfect for those who majored in Chinese studies or communications, not for the average Singaporean.
The HR that dealt with me at that time was also very unprofessional. She kept going on and on about this one guy who's the PERFECT candidate, on how he's the best, yet he didn't accept the offer because he found a much better one. This happened during my interview with her. I'm sorry that you didn't get the perfect candidate but please keep your emotions and professionalism in check.
