Terrible interaction. Recruiters spam your linkedin and do not communicate clearly about the job. I got told I would receive a reaction the same week. Two weeks later I got a rejection! They told me they've enjoyed talking to me but that I would lack ''interpersonal'' skills. That while they weren't honest with their reaction timeframe towards me in the first place. Extremely unprofessional. I guess they expect candidates to bow towards the boss and show no backbone. If you have a functioning brain I would recommend to choose from one of the 50 other or so consultancies in the Netherlands that provide a similar service.
I think with such a terrible HR department I wouldn't trust working for these people. Just from my brief interaction I would even go so far as that I would not want to have any engineer, developer or whoever from this company as a consultant. Their only abilities are within the domain of stroking the boss's ego.
