Its just a scheduling thing, line up all your interviews into a single week. Similarly, when they start coming back, push them out into the week following so you have room for the slow responses to catch up.

You can reasonably fit in 5-6 interviews into a week.

While working full-time? Not everyone can afford to take a week off of work just to interview at companies that may not necessarily extend you an offer.
