Yup, our clients have brought this up with us as well, which is why we recommend they offer 3 choices for the candidate to do the interview:

1. Hop on a call, do the interview in one sitting together and share thoughts/questions

2. Hop on a call, make sure set up is smooth, prompt is clear, questions are answered, then candidate goes off on their own. Hop on another call later in the day to demo the solution and talk over design decisions.

3. Do it completely async, submit the solution whenever you have time

From what we've seen, this flexibility has simultaneously reduced dropoff rate and increased candidate experience, since we're catering to the candidate's needs. Some would prefer to do it face-to-face, others prefer to work on their own.
