sorry but I do not see this as useful. I just use a spreadsheet and that is good enough. The hard part of job interviewing is learning all the useless Leetcode and preparing the stories in "STAR format" and interviewing taking up 5 hours and the indefinite period of time for replies. Not the tracking.
To me the hard part is finding a company that doesn’t rely on this when interviewing (I consider it unnecessary and inefficient, I wouldn’t want to work in a place like this). So a tracker with reviews sounds good in theory.
Same, although I appreciate the work OP's putting into this, and would find value in the aggregated statistics (especially stats about the interview funnel.)
For me, I just have a big plain text file where I keep notes and stuff about companies once they get back to me after I send off a resume. I also have two email folders (one of all job search related stuff, the other for messages about upcoming or pending calls) and iCal.
Tracking which job you applied for is the least of the job applicant's concerns when looking for a job. In some circumstances the first step of the job application process is even fire-and-forget, and tracking those only serves to not apply again which is a zero-effort move.
Once you start to get a process going, emails and calendars already leave a good, easy to follow paper trail, and any need you might have is easily fixed with a text file/spreadsheet.
