Looking for the First Job state

Looking for the First Job

Versão em Português

This is a very common state for people in college, people before/after a bootcamp, or people from another area.

The first job will be the hardest one to get, but it will get easier over time.

The interview will be harder than the job itself

Memoize!!! 💾 - a react (native) performance guide
In computing, memoization or memoisation
is an optimization technique used primarily
to speed up computer programs by storing
the results of expensive function calls and  
returning the cached result when the same
inputs occur again.

Most job post are about requirements that you should already know.

We think that you should learn a lot when working for a company.

So here is a list of many things that you are going to learn while working for us (and many more):

  • how to use git to work in a team
  • how to contribute to open source projects
  • how to manage .env files (configurations)
  • local vs staging vs production environments
