Eh, people mess up sometimes. If the apology seemed sincere and you actually want the job, I would give them another chance. If not, don’t.

I generally use ‘count’ for a counter and ‘idx’ for index.

I’m not using C or Java languages though - if I were I would probably go with the more classic terse approach.

Also, if I’m reviewing a PR and I have to load more of the diff context to understand what a variable represents, then that variable has the wrong name.

I’m honestly prefer short but (usually) complete words. Somewhere along the line I realized that being explicit really helps when you need to change it later.
