Is VXI that bad?

I've already signed their JO for a 20k basic salary and nakita ko mga reviews ng VXI dito, and I'm scared.

This will be my first job, at 19 (stopped studying Nursing muna) and I am in telco, supposedly, it's one of the hardest account. Super toxic daw ang management in this company, and I'm wondering if I can survive for a 1 year, or if 6 months is even doable.

Any tips/advice for a newbie like me?
