No, it's really not. I've been involved in hiring at multiple American companies. One page is not important. No more pages than you need to highlight your highly impactful experiences is much better advice.

If you're incapable of fitting your experience into 1 page (when that's the prevailing standard), it makes me seriously question your critical thinking skills

You are a special snowflake.

It does seem to come up a lot on HN whenever the topic comes up, yeah. Though the odds are high, OP might not be American -- and besides that, others will read this thread as well. Perhaps it would be better if we mentioned where on the planet we are when discussing things like this.

That said, 1-3 is sort of acceptable depending on how relevant the information is. But 4+ pages would definitely get thrown in the circular file.

What we DO give a shit about is what's actually in it.
