NOT RECOMMENDED TO ANYONE!
The 4 interviews I had all went well, although being way too long in total. Besides the HR, I had a meeting with four different persons, including 3 techies, through the process. The questions on the tech interview were of moderate difficulty, some a bit simple though.
I had to decline the offer because the salary proposed was ridiculously low. That was actually looking as an attempt of fooling a person supposedly not fully aware of the local tax system. Negotiation followed didn't help either. Finally, I was insulted by their HR blaming me with an absolute bs about me.
A very negative experience at the end.
