Avantages
None. They are irrelevant in the industry and they don't care about their employees.
Inconvénients
I was headhunted by an Airspan recruiter who told me they need to urgently fill the position. At the time I had 2 months left on contract with my previous employer. I went through the interview process where I was told again that they need to fill the position ASAP and they cannot wait 2 months for me but they did offer me a much higher salary. They sent me a contract offer which I signed and within a couple working days they inform me that the position is closed due to restructure and they will pay me only 1 week notice. So Airspan HR is telling me that within 1 month they went from having to fill the position ASAP to a restructure that closes the position. Bottom line, I lost 2 months salary from my previous employer which I would have kept if their recruiter did not insist on me starting ASAP and Airspan left me unemployed in the middle of Christmas. I have never encountered such incompetence in HR and management in any other company. Avoid them at all costs, they don't care about you.
