By tracking all of the things on this spreadsheet, you’ll be able to see what applications go well and compare why they might not be successful. For example, making note of the company, pay, experience level and location can show you how competitive it might be. If the pay is £25k for an entry level role (does that even exist?), you’ll know that the competition is high so don’t feel bad if you don’t get it.
By plotting in which stages of each application you get to – whether that’s an interview or a final stage – you can see what areas of the application process you might need to tweak or do some more preparations for. If you’re getting a lot of telephone interviews but not getting beyond that stage, see if there’s any more research you can do before the next one to really get your phone interview skills up to scratch.
Also, when you apply for a job, take a screenshot of the listings and attach those photos as a file in this spreadsheet. That way you’ll always have record of the requirements and job description if it gets taken off the site.
