Using an actual problem you solved can also work against the candidate because most problems we encounter in our daily jobs require a lot more time than the standard 45 minutes reserved for an interview (actually only 35 minutes out of 45 because there's 5 minutes of intro/icebreaker and 5 minutes reserved at the end to answer any of the candidate's questions).

So it isn't fair to ask the candidate to solve a real bug or implement a real feature in only 35 minutes unless they've seen something similar before.

This is why big companies like Google are limited to whiteboarding interviews because they need to have an interview process efficient enough to properly vet and filter >1 million applicants Google receives each year.

Personally, I think a better interview process is a pair-programming or work audition for a day. But that is not even close to matching the scale of Google.

Let's say out of a million applications, maybe only 25% are qualified. That is still almost 1000 candidates to interview per day (number of U.S. business days in 2019 is 261; 250,000 candidates / 261 business days = ~957 candidates per business day). Pair-programming or full day work audition will not be able to accommodate 957 candidates every day.
