[US]My husband was targeted by what I’m pretty sure is a job scam involving a questionnaire in place of a job interview

My husband received an email from someone claiming to be a recruiter. Their email was a person at companycareers-com email stating that they found his resume on LinkedIn and they wanted him to fill out a questionnaire of how he would handle different job scenarios and that this would take the place of a traditional job interview. He sent them back the questionnaire with his answers and the next day they sent him another email saying a job offer was being prepared and the included job offer listed an amount of money he would be paid per month. They said he would need to buy a computer and software for the job but this would be reimbursed. I had a weird feeling about the whole thing and I checked the company’s website and the job isn’t listed on their site and the only job posting similar to the job was supposedly waiting on an offer for was for substantially less money.

This is a scam right?
