Track Your Applications
Seeing some Entry/Jr Coders talk about submitting 200+ applications - I mentioned this in my infographic thing I posted yesterday, but want to emphasize it more: If you're not tracking where you've applied you absolutely, 100%, need to be.
It's not about creating a list to keep count - there's important data in there. If you've applied to the same company 5x and they're bad about getting back to you, save your time. Or maybe it helps you save face from applying twice to the same place. If you're bad about remembering when you should follow up - tracking your next actions will help you. You can even get more analytical with it: Say you just updated your resume, and suddenly you are getting more responses (or less responses) - you'll be able to track that.
Lastly - you 100% absolutely should mention this in the interview. From my vantage as a hiring manager, hearing how someone organizes their job hunt tells me so much about how they'll organize their work load.
You can use my simple spreadsheet I'd made
Or use a service like Huntr
Or this one from Muse:
Just track things!
