Things You Should Know Before Your First Software Job

How do you teach yourself?

Take notes

You won’t refer to all of them, but the act of writing things down helps remember.

Set up backups/cloud syncing

You should ensure that if, tomorrow, your computer were to fail, you won’t lose any data.

Figure out what to memorize and what to keep in reference

You probably don’t need to memorize it… but if you do, you need to work at it.
