Open day, there are 3 interviewers to make this event. And i went there at 830am, wait until 4pm only able to pass up my cv. There are a lot of people (maybe more than 500 people plus).
The things that i advise for you:
1. Even you come early make sure yourself go in the room as early as well. (Because i get cut line by other candidates, even though there are good candidates come late also cant get the offer for the assessment day)
2. Do registration before you go for the open day. (Recruiters will ask you to write your candidate ID on the resume)
3. Talk with other candidates, this actually able you to talk more fluent with the recuiters.
4. Sad to say, if you didn't get the paper from the recuiters mean 90% you get it fail. Because they will give you an invitation for next day, at the same time they also will say please wait for the sms/email/qatar account before 12am at the same day. But none of us get it, as we all know this is the lie.
However, when you are first time to go this event you will feel like super tired. But you able to meet different type of people want to achieve their dream. Fail doesn't mean anythings, we can always try on it.
