I don't because I am an independant recruiter and work on just a few positions at a time. If I had dozens of reqs like corporate recruiters often have then I would probably use Excel. When I was a corporate recruiter (seems like a lifetime ago) I did indeed use Excel or some other spreadsheet.
I tend to put alot of notes or reminders to myself in Outlook Calendar on next steps with hot reqs and candidates.
Corporate Recruiter - and like Amy I use an ATS that only I look at, and I also have weekly/monthly/quarterly/yearly Excel spreadsheets, again for my own use (though I have sent them to my bosses to show all of my activity when things get chaotic). If I didn't track, there is no way I'd remember all of the Candidates and jobs I am working on!
Agency - i use color codes in outlook and calendar reminders. Also set up file folders in outlook and copy resumes into folders when they are submitted on a job. Folders are named, dated ,closed when filled and moved to a different section of outlook inbox. Fast reference to good candidates and full write ups for the next "same type of job". No spreadsheets, i hate filling out forms.
Definitely need to keep track of things. Also, hint here. you can also use that same spreadsheet to keep copies of your best search strings and G2 info for that search
Me too maintain and update my own db.Its best way to keep it organised and handy.
Oh yes, it drives me nuts.
Excel - sometimes Google Drive Spreadsheet when collaborating with multiple people.
