There are a lots of unknown people asking the person to wear formal suits without any further details. However, the interview seems like going to attend for a bunch of group interview. It's quite a weird interview sessions who might ask someone to interview in a group form
Everyone is well dressed and energetic during the interview.
Svantaggi
Interviewer will give you very good image about the company keep mentioning about teamwork spirit and gaslighting you. No EPF / SOCSO , talking about work life balance but need to work 6 days a week 9am-6pm (only can choose to rest either SAT or SUN)
