Pluspunten
I've been working for them for more than a year now. Sometimes it really sucks when you have a bad day but if you're smart you are not giving up so easily. Payment is not that great but if you work for a webhosting contract you get a lot of very useful and valuable knowledge that you can get no where else. At least not for free. Sometimes when they promise you a bonus you have to fight for it for months. But if you are persistent you will always get what you want. Thats how they kind of teach you to be more persistent. Very valuable for life in general as well
Minpunten
If you wanted to, you could see many of the pros as a con as well. Low salary for instance or that sups or management are not very knowledgable. I can see that some people get frustrated about that and then leave. I just don't want to leave because I'm intrested in what I'm working with right there. If you're a stubborn person concentrix is good for you. Because it appears that thy want to teach all of their employees to be more stubborn in order to get what they want
