Job interview - point out mistakes?

[quickque]

As a candidate and at the end of an interview with multiple interviewers would you bring up noticing a mistake the company had made?

E.g - spelling mistake on the website, tracked changes showing on JD, formatting issue / grammar error on blog post?

Depends a bit on the job and how they were saying it. The interview for my current job I talked quite a lot about how their current systems can exclude people (people with learning difficulties or without strong English for example) but it was in the context of how I would support under represented groups. I was very critical of some things they did and I still got the job.
Just telling someone their website is a mess without context or relevance is smug and an odd choice.

I had a TA like this when I was teaching. She was so full of herself and we couldn't understand why she'd been employed.

It came across as extremely smug and irritating and no one wanted her in their classroom. She had no idea how to work in a role without criticising others.

Nope and if someone did that to me they would absolutely not be getting employed. There’s a time and a place for that and during a job interview isn’t it.

Sadly, she had poor spoken grammar too which made it even worse.

If I interviewed someone who said that I'd would appreciate it. If I'd been so slack as to put out an advert that unprofessional I'd want to know about it.

Anyone doing this would be demonstrating an extrodinary lack of tact which would in all likelihood make them annoying to work with.

Ha not if I wanted the job, no! if it was a written error, the writer may have dyslexia or English not as their first language in which case it would come across very rude.

On one occasion when I was much younger, I went for one of these jobs selling makeup in the street and the interviewer tried to bullshit me saying that MAC had started 3 years ago selling makeup in the street, suggesting there was huge money to be made. I knew this wasn't true and called him out. In this case I am glad I did as it was a fabrication, but an interview isn't really the time to be correcting genuine mistakes (unless asked). And no, I didn't get the job!

No. It would mean you probably would t get the job. Tact and understanding social rules is more important when you work with someone and than them being right.
