Gentex Corporation interview questions

Very easy going, personnel was very polite and attentive to my words. Initially I applied for a different position and they called me saying that I was a match for the Operation System Engineer position, they are very transparent and professional.

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.
