Depends on your level of honesty. Given that you're fixing typos to say that you contributed to a project, you'd probably double down and quote the number of PR

Depends on your level of honesty. Given that you're fixing typos to say that you contributed to a project, you'd probably double down and quote the number of PR (remember to only do 1 typo fix per PR) and then add a real bug you may have fixed or make one up. Unfortunately the entire interview process is why I usually try to hire former co-workers.
