Slalom Network Engineer interview questions

Thoroughly disappointed by the company and the whole interview process. I attended 6 interviews, met with 9 different people and wasted numerous hours. Most of the people I met with via Teams were from the US, so I had to attend the calls in some cases after 8-9PM. After the whole process finished and I was assured that I am a great candidate and everyone is extremely happy with my performance one of the recruiters called me and said "You did great, however we are actually in a hiring freeze, sorry. The position is no longer available". HE then reassured me that the position will again be available in a few months and he will keep in touch with me. Of course that never happened and I have never heard from him since. This has never happened to me before and it is unacceptable.
