I just made a spreadsheet I added to over time to track this type of stuff for myself. It is interesting to see the process in a graph [0]. Would be really interesting to see this data aggregated for industries or specific positions.
Most of the interviews came from younger tech firms, which were more lenient (and also willing to hire less experienced individuals due to budget constraints).
300~ applications. ~25 actual rejections. ~15 phone interviews. ~5 onsites. ~1 accepted.
It felt both necessary and successful, considering the junior dev market is flooded and treacherous.
Since then though, it's been basically through specific personal connections with essentially no applications as such.
