I appreciate the encouragement, but in my particular case I'm pretty clear on where I goofed: - For two of the positions, I wanted to get more into LLVM (internals) development, but didn't have enough prior experience to get the position. - For one position, I had to give a presentation on some aspects of an LLVM back end. I think my presentation was just too clunky. I used too much of my prep time getting up to speed, leaving not enough time for putting together a reasonable presentation. Or I just didn't know enough about LLVM back ends (at the time) for the position; hard to know. - For one position (Waymo), I did badly on a live programming exercise. I hate them, but it seems clear that I need to spend some Saturdays practicing LeetCode-type problems. At least if I want to work for an Alphabet company.
