How do I find people to interview for UX research?
Posting a Google Form on LinkedIn, Facebook, Twitter, or even Slack groups can be a good way to find research participants—just make sure you have a robust screener prepared to weed through unqualified candidates, since you'll likely get a lot of them.
How many interviews are enough for UX research?
