Tips
Irrespective of you applying at Armory or not, some of the following tips will definitely help you in your job search.
How to get hired
Targeted Applications: Ensure your application is tailored specifically for the job you're applying for by understanding its requirements and showcasing relevant experiences and skills. Apply for THIS job, not some job.
Quality Over Quantity: Instead of applying to 100 jobs casually, it’s far better to apply to 4 seriously.
Stand out: Most people don’t put any efforts in applying to jobs, their applications look exactly the same. It’s easy to stand out from them just by putting a little effort and showcasing your relevant experience and interest for the said job.
How to NOT get hired
- If your cover letter starts with _“Honestly, I possess all the skills and experience that you’re looking for”_, then you are not going to make it.
- In fact, we wrote a long thread on all the ways you will NOT get hired. We highly recommend you to read it.
