This was a comment I made on another ranter's post.

* Tailor your resume (and cover letter if needed) according to the job. No generic resume.
* Research about the company and make sure you have the same interests as the company. Clearly let them know why they should hire you. One question you can expect is: Why should we hire you?
* Show them that you're passionate about the job.
* Be curious. Ask questions. That's how they'll know you're interested.
* Be open to opportunities. Let's say you're applying for Full Stack developer role. Be open to take up Front End or Back End developer role. You don't have to accept everything but at least roles tangent to your job (provided they match your interest).
* Be flexible but focused.
* You don't have to know every listed requirement but make sure to know the majority.
* Don't lie. "Fake it till you make it" doesn't work with dev roles.
* Be confident in telling them "you don't know" if you don't know. Also make sure to tell you're willing to learn that.
