IDEMIA Junior Project Manager interview questions

The interview was split into three stages: IT Manager, HR, IT Director interview, on separate days. I passed all of them and I was promised that within one week I will get a reply back. After 3 weeks I called them, they did not answer. I sent them an email and I got called back, and promissed an answer in a couple of days. That happened over a month ago, almost two. This by far, was the worst experience I have ever had with a company. The lack of respect is incredible, I cannot belive how this company treats potential employees. I do not reccomend.
