Keep Track of Your Job Applications
However you do it, you need to keep track of your job applications. It doesn't matter if it's an index card, a dedicated notebook, sticky notes on your wall, or some sophisticated tool on your smartphone. If you don't keep track, you're not really showing that you're dedicated to finding a new job.
One of the best ways is to create a spreadsheet to record details and status of each application - what / when / how / who! Record which CV you've sent (as I hope you're fine-tuning your CV to the job each time) - so that you'll know which one was sent if you get an interview! - make notes about follow ups, contacts at the company, key company news.
By keeping track, it shows that you're organised!
