it was hard with 8 interviewers. it took 3 months and at the end I had the email offer. after one month they sent me a not and said they wont give official offer. Would it be even legal? I wasted my 3months of time to find the position right before major semiconductor manufacturers starting layoffs.

Too many interview layer and taken too long involved many level interview. It take almost 3-5weeks. Hiring process also very slow from interview till offer which taken near to 1-2 months. Offer not so attractive

The interview was Fair and technically oriented interview. Went in lot of details for FPGA architecture, RF shielding, and thrmodynamics. It did not feel like an interview for management position.
