3. Decide where the person can work. 8% of today’s kernel and operating systems engineer postings are remote and 18% hybrid. If yours is remote, name the countries or time zones; “remote” alone brings applications you cannot accept.
4. Post it where people look. Post the job free on this site, add it to your own careers page and send it to people you know who do this work.
5. Screen for the work, not the titles. Ask each candidate to describe a result from similar work, with a number. Score every candidate on the same points with the interview scorecard; the kernel and operating systems engineer interview questions show what good candidates prepare for.
6. Decide quickly. Half of today’s open kernel and operating systems engineer postings have been up more than 79 days: a candidate who waits for your answer may be talking to other employers meanwhile. Tell every candidate when you will decide, and keep to it.

• Use a real, anonymised task from your own work: the kind of problem the person will meet in the first month.
• Keep it to two or three hours, say so, and pay for anything longer.
• Ask for three things: the result, how they got there, and one recommendation or next step.
• Score every answer on the same points: correctness, clarity and judgement.
• Talk it through in the next interview: how they explain their choices tells as much as the result.
• Not sure yet? A short paid trial project or a contract-to-hire term lets both sides check the fit.
