It can definitely be overwhelming. Try a spreadsheet for tracking, and a calendar app for scheduling. Figure out when you have time to offer, and suggest 2 or 3 times that work for you when scheduling. Don't offer the same times to others until you hear back. Religiously update and follow your calendar app.

For the spreadsheet, similar to mead5432's Trello suggestion, the columns could be:

Date applied | Date last contacted | Company name & role | Screen or interest | Challenge or coffee | Onsite | Offer | Accepted | Notes | Person contacted | Resume & cover letter links

Screen or interest, challenge or coffee, onsite, and offer are binary for me (X or empty), and can help you see if you're getting stuck on a stage. It can help clarify where you can focus your energy to get further. For example, tracking these things might help you realize you get few or no offers but many onsite interviews, and with that awareness you can focus on getting better at onsite interviews.
