There's definitely an underrepresentation problem (most grievously with female engineers), but I sincerely believe the problem is mostly systemic, rather than driven by personal prejudice.
From my (limited) perspective, the only thing anyone gives a damn about is whether you're a good developer. If you can code, if you can ship, if you can work well with your other colleagues. Please don't feel like you have you walk into meetings pretending you're somebody else. Walk into meetings with the confidence of a great engineer and founder - because anybody who gives a crap about anything else isn't worth impressing.
With love, from one engineer to another ️
