Question
I have come across a startup in the very early stages, and I'm interested in working with them. They recently posted a job opening for a web designer and I want to apply. Is there any specific thing I should do regarding applying to a startup? Like a cover letter or something else?
Answer
I'd suggest calling them or contacting them directly and asking what they need.
In my experience (launching startups and coaching them) - owners and principals are interested in attracting passionate and talented people to joint the team.
Certainly be ready to provide them with a resume or a CV if requested. But also be ready to share with them what YOU will bring to the team and to the company to help them succeed.
Best of luck!
