Ericsson Data Engineer interview questions

I was interviewed at Ericsson for mid level data engineer position. Two interview rounds happened followed by a salary discussion. This took 1 week. Post that they said we will release offer letter later due to there offer letter tool is freeze. I waited for 3 weeks and then another HR told me the hiring is also freeze. This is there normal procedure, I have heard similar case of one of my known person. Moral of the story: Don't think you will get offer letter even if salary negotiation has happened.

Good first leavel and second leavel and than manager level and finally with HR . With each step if you gets selected than another round scdeule and further going on till thrird round. Finally selecyed
