WHAT’S THE INTERVIEW PROCESS LIKE?

The process can differ between roles, but we usually start with a quick screening call followed by in-person interviews to be sure we’re on the same page and a good fit for each other.

1. Quick 45 minute screening interview to make sure we are on the same page. Here, we try to briefly understand cultural fit, where you’re at, what you’re optimising for, strengths and weaknesses, relevant experience, etc.
2. 1–1.5 hour deeper interview with the functional lead. There may be some overlapping questions here — we don’t compare notes between interviews to keep the process independent.
3. [Only certain roles] 3–4 hour practical interview.
4. [Only certain roles] Interview with CEO/COO.
5. Reference check.

If you have read this far, some useful tips:

• Always follow up after each interview - tell us things you learned, what you enjoyed, why you would be a good fit, ask more questions, supplement your answers — this will go a long way!
• This is a basic detail but people fail at it and we are the kind of company that likes helping you out — reply all in your emails. Make sure everyone that needs to be in the loop (especially your champions in this case!) are to/cc-ed in each thread.
• “Any questions for me?” → The right answer is always yes. And belt out the 3 questions you prepared for this interview. Some good questions: “How did I do in this interview? Please give me brutal feedback.”, “Pre-mortem: If I joined Grain and I was no longer with you all in 6-12 months. Why?”, “What do you think are the most important traits for this job?”
• Pro tip for sales interviews: Sales is more about asking questions, instead of talking. Learn this in 1:38 minutes here.
