First would be the HR interview, basically they'll ask you if you know about technical stuff about phone, laptops or computers. Then they'll ask for an example of a troubleshooting you've done to one of your devices.
Once you passed that, then comes the aptitude test and the typing test.
Then the final interview with either one of their team leads or trainer.
Once you passed the final interview, they'll give you the job offer. All done within the day. I went there around 1pm and then got the job offer around 12am.
