1. Attitude and values
- Are they rational, authentic, and honest?
- Are they curious and enthusiastic?
- Are they optimistic and cheerful?
- Do they take pride in their work, being good at their craft, and having an impact?
- Do they have a growth mindset?
- Are they low-ego, respectful, win-win, and collaborative?
If a person has a misaligned attitude or values, it's better to say no, even if they have high capability and interest.
2. Capability
- Do they have the raw smarts and foundations to learn and grow?
- Do they have the required functional skills at the right level of the job?
- Do they complement the team's skills and bring something new?
- Can they communicate and collaborate well?
- Do they have a similar previous experience with good work and insights? (less important if the above are strong)
3. Interest
Deep interest is a multiplier for both attitude and capability.
- Are they interested in the mission and domain?
- Are they interested in the customers?
- Are they interested in becoming better at their function and craft?
- Are they interested in building team culture and collaboration?
All of these apply if you want to be valued as a team member and generally be happy at work.
