I took a coding boot camp when I decided to leave academia to join industry, and it was a useful primer on the “in” technologies that folks would be hiring for, and of the “style” of code that was fashionable at the time. I would not have hired any of my classmates (well, I might have hired one as a junior), but the bootcamp did what I needed it to do, exposing me to the “culture” of programming at tech companies.
I was hired as a mid-level and quickly progressed to senior at a large global tech company. I have been at a few different tech companies now and haven’t run into any major challenges or problems, and have only received positive feedback from my peers and managers.
If I were evaluating who I was then as a potential hire today, I’d probably consider me a risky hire with unknown potential. I think it helped that I had a number of usable “products” that I had made over the course of my career as a solo programmer that didn’t really fit any mold. I also think it helped that I didn’t have any trouble with basic algorithm brain teasers, finding them sort of fun at the time I was interviewing. I’ve never tried leetcode but I suspect I’ve only seen leetcode “easies.” Thankfully I haven’t had to do any of that for any of my subsequent jobs as I don’t think I’d have the patience for it anymore.
