Well there are a number of ways you could handle the situation:

1. Ask if you could think on it for a bit to buy yourself some time to finish your other job interview and then make a pros and cons list of working for each company to decide.

2. Accept the job from the smaller company but keep doing the interview (Who said you can't have two jobs?) and then just work at both companies.

3. Accept the job from the smaller company and end the interview.

4. Decline the offer from the smaller company and prepare for the interview in the meantime.

5. Accept the job from the smaller company and keep going with the interview process and if you get accepted you could use that as leverage for a higher position in the smaller company.

I don't know your exact situation but hopefully this helps.
