Applied online. Two days later, asked to take an online skills evaluation, consisting of 6 problems, for which I had to write a C function. The problem statements were poorly written. The coding was fairly easy, mostly array manipulations. No hard core embedded problems, like bit manipulations. I finished 2/6 problems. 2 of the "fails" crashed their system when tested; the other two "fails", my time expired. If I only had 1 or 2 more minutes on each. Two hours after this evaluation, I got the automated rejection.

Very lengthy, went through a grand total of 7 interviews over 4 different days. Included technical programming tests, phone interviews, two virtual interviews, and a day of four in-person interviews.
