Is it OK for a company to expect using their paid product for a job interview?
I had a job interview with a company recently and one of the negative feedback I got was that I hadn't tried out their product. Now this might be a valid concern if they had any sort of free trial for it, but the lessons they offer start at 60€ and I didn't feel comfortable spending that amount just to get a better chance at an interview. They also offered no free credits or anything like that during the interview. I did understand how the product worked by researching it online.
I definitely feel that there's something wrong in asking for an interviewee to spend money on the product they are interviewing for. For one it's a great setup for a scam. But is there any regulation that should prevent companies from doing this? I am based in the EU and was interviewing for a Spanish company.
UPDATE: This is definitely not a scam, the company is fairly known. This is more of a question of is it right/legal to expect this?
There are certainly commercial (enterprise) software suites that many jobs would expect you to have familiarity with. If you were applying for a job with Atlassian then yeah I'd expect you to have familiarity with JIRA at least. There are lots of instances of businesses expecting you to have experience with specific not-free software, but it mostly falls under the category of work experience.
