Pros
Summer vacation in good hotels but it's not for you. It's for their customers.
Cons
TL;DR: No. Just no. Anything else is better. Long answer: It's not worth it. If you want to get experience but you are willing to sacrifice your mental health then OK go for it. There is no "competitive" salary, no good environment (actually there is no environment at all). There are no perks. You are a tool. This is not an IT company but a PEO company which "rents" employees to other companies. From time to time they might get an internal project but it's temporary. They are going to categorize you as "billable" or "unbillable" depending the project you are working on but if you are "unbillable" you might get fired no matter how much you provide to this company. A good example is the secretary of this company. She got fired without warning and she left the company less than a month. Legally they need to give you a month. It used to be a company with really good employees who worked a lot and sacrificed their personal time to make this company bigger ignoring their own interest but management ignored them for their own interest. You could make some good friends but now there is nothing left. The biggest problem of this company was/is management team except one person (Nikos). He was the one running this company and the only reason most of us stayed. He just left and now there is no reason to apply for this company. Any other job is better than this. If you are going to work for this company, this is what you are going to deal with: low salary, no matter what they are going to tell you, you don't get a raise every year, you have to ask for it and you might feel like you are begging for it, after all you might get a pizza and that's because they can declare it as company expenses. You are just a tool after all. Management will change opinion day by day (yes there is no "manifesto" after all these years. They failed to create one for personal reasons) and you might end up dealing with problems you didn't create and at the same time you will watch them explaining themselves with sophistries which is insulting at least. If you do something they don't like or have an opinion they don't like, whatever it is, the threat is always the same, "this is against the policies or the interest of the company and it's a reason to get you fired". I am not a lawyer but in my mind this is an extortion. Keep in mind that "the company" is one person. If you really want a proof of what is happening, check here, in Glassdoor, the dates that the first negative comments appear and then the datetime of the first positive ones. The positive comments appear after the request of the CEO to previous employees who cares only for PR.
