I have a leaderboard of some of the longest turn-around times from initial contact to rejection. Thus far the winners (if you can call them that) have been:
Docusign (4 YEARS); Nintendo (34 months); Google (30 months); Starbucks (22 months); Netflix (18 months); Astral (13 months); Snowflake (8 months)
But I also have a short list of shortest turn-around times. I say this because some of them are truly insane:
GitHub (3 hours); Valve (4 hours, but it was a real human with actual comments); Lockheed martin (2 hours); UserTesting (1 hour); Mozilla (30 minutes); Cloudflare (-2 minutes); Matterport (0 minutes)
The -2 minutes you see there is one of the most insane things I've ever experienced: As I'm filling in the application, I get an email simultaneously thanking me for going throug the recruitment process but saying they "reviewed my application" (that hadn't even been fully submitted yet) and that I wasn't a good fit for the role.
Matterport wins the award for "well at least they're not bullshitting" -- as soon as I had submitted the application, I didn't even get an email saying thank you, just a straight up dialog box saying "You won't be considered for this position."
My worst experience was with Microsoft. Somewhere, their system is designed such that if you ever fall out of the standard process, you're "rejected" -- I have more rejection emails for a position I ended up getting (which got canned within the year, ironically enough) than any other kind of email, including daily emails with the recruiter and hiring manager. I got an email telling me "sorry no thanks" *after* I had already signed the paperwork.
