Just imagine what would they ask a published novelist, if they wanted to hire one:
- do you know what a comma is?
- please, tell me something about words.
- how do you write a word using letters? you know about letters, do you?
- could you please write a question? just any question.
And after he politely pointed out that he obviously knows all of that stuff and much more, they switch to "advanced" questions:
- have you ever heard of an "oxford comma"? (in a very suspicious voice)
...
That's my very recent experience with one very large international investment bank. Almost literally.
Sadly, that's how many of the large companies think it should be done. Not even kiddin', I was really puzzled the last time that happened.
Luckily, even tho it's a weird experience, you now know where not to apply next. Hope you'll find the perfect fit!
