Take-home programming assignment for job applicants? Good or bad?

Is it better to have software engineering candidates code during the interview or let them do it from home?

Since most engineers are introverts, my guess would be that allowing them to code from home could better demonstrate their skills. What do you think?

Yes, good idea!

Reasons why:

• If a candidate is willing to do a small programming puzzle or assignment from home, it's a good signal that they really want to work for your startup. Someone who doesn't, likely won't revert back after the in-person interview.
• They will be more relaxed to do it properly.
• It's not cheating if they're researching things online because that is how engineers work. Googling for reference is an integral part of how they'll be working when hired.
