How do I get into technical writing? Majored in English.

Your major weakness is most likely the inability to think procedurally. Get good at examining assumptions and breaking objectives down into steps and you'll be a decent tech writer.

It's not actually about the writing, it's about breaking big steps into smaller steps.

Here's an exercise: Write the process on how to boil an egg/replace a toilet/etc. You should be able to break it down into at least 10 steps. This was a real interview question at a software company I worked for.

An example of your work.

Not OP but wondering what would be wrong with the following:
Fill a pot with water
Place filled pot on stove
Set heat to medium
Once water is rolling boil, place egg gently in.
Let egg cook for 10 minutes.
Once time is over, turn off stove.
Rinse out only the water from stove.
Take egg out and let it cool.

This is barely sufficient. You can break it down further and be more exact with your commands. Where are the eggs located? Where to get water from?

Plus you did not address any bad situations at all. What if there's no eggs left? What if the stove doesn't turn on?

These things are telling of someone that has the right type of thinking for the job.
