- As others said, you should post your salary. You'll likely need to be competitive in the markets you're hiring for. If you're open to folks within the US as fully remote, you'll likely want to be targeting the 50-75th percentile of salaries for the YoE you're looking for.
- The take home of 4 hours is quite a lot of time end-end. I'd consider slimming this down to 2 hours if you can OR allowing candidates to have several days where they can work on it at anytime vs being timed.
- It is extremely hard to stand out as an individual company nowadays. There are a truly amazing amount of startups, mid-size, enterprise, and beyond, companies hiring engineers of all levels. Without a way to tap into a market which you may serve organically and leverage those users into potential candidates, it's just going to be tough to stand out.
- You likely will need to spend time sourcing yourself and investigating a variety of avenues where you either a) spend your time sourcing / using a tool that helps (such as triplebyte / AngeList AList) or b) bring on an external recruiter. I would suggest bringing on someone that is actually technical and has a history in engineering, which is likely tough to find.
- Feel free to email me if you'd like to just chat more about this bit (external recruiting). We're happy to help, email in profile so-as not to simply self-promote within the comments. As a simple plug, we specialize in providing mid-funnel engineers for hard-to-hire roles and are happy to take over the first third of most engineering hiring processes.
