It's not uncommon for employers to request GPA and/or transcripts. Source: I graduated 2 years ago.

I've never been asked for GPA or transcripts (been graduated since 2012). YMMV, depends on where you apply I guess.

I graduated in 2008 and was asked for my GPA when I applied somewhere in 2015...but that was an unusual case. One place out of dozens.

If I see a resume with any GPA but a 4.0, I generally laugh.

If you got a 4.0, sure put it on resume. But a 3.2 or a 3.6? Silly, leave it off.

I always get them without even asking (Europe). I never received a "diploma" however. Only transcripts of classes.

It's usually obvious from the ones I see (I don't see diplomas I get transcripts with classes taken, dates they were passed, and grades)

The usual sign is someone e.g getting a masters degree 2000-2005, and passing the introductory math classes in 2005.

Your metric will lock me out:I did Real and Complex Analysis sophomore year but was forced to take intro to statistics senior year in order to graduate.

That kind of thing is in every transcript. Doesn't look strange at all with the odd one like that. It's rather systematic failure I'm trying to look out for.
