Hi there,

Thank you for reaching out. I'm always interested in exploring new and exciting opportunities out there. As a software engineer I'm sure you can imagine that I get a very high volume of recruiters reaching out to me. It's a wonderful position of privilege to be in and I'm very thankful for it.

However, this means that I have absolutely no time to personally respond to every single one. Unfortunately most incoming messages do not match my ambitions and level of knowledge anyway. While I very much appreciate the fact that exceptionally talented and engaged recruiters reach out consistently, sorting serious and high quality opportunities from spam would be an actual full time job for me.

I would love to continue the conversation, but before I do, I'd like to level set around the level of seniority that you're looking for. Can you send along the company name, a job description and, total compensation details for the role you're reaching out in reference to? In the absence of detailed information rega
