Typing speed matters in a coding interview. You get maybe 30 minutes to write a bunch of code and answer all the questions on the fly. The network connection and speed of your computer matters.
Interviewing sucks.
I’m a fast typer. I’m really really really glad I took that “way back” high school touch typing class seriously.
Some of the most legendary programmers I know are hunt and peck typists.
So… how fast you type doesn’t matter. It sure is nice though!
