A 'tech stack' is the set of technologies used to build an application. Frontend: React, Vue, Angular (JavaScript frameworks). Backend: Python/Django, Java/Spring, Node.js. Database: PostgreSQL, MongoDB, Redis. Cloud: AWS, GCP, Azure. DevOps: Docker, Kubernetes, Terraform. Understanding these layers helps you assess candidate fit.
Technical Recruiting Guide
Recruit developers confidently. Understand tech stacks, skill relationships, and how to assess technical candidates.
Technical recruiting is challenging for non-technical recruiters. You need to understand skill relationships, assess experience levels, and communicate credibly with candidates. This guide breaks down the essentials of tech recruiting.
1
Understanding Tech Stacks
2
Skill Relationships and Equivalencies
Skills are related. React developers know JavaScript. AWS experience suggests cloud knowledge generally. 'Full-stack' means both frontend and backend. Python can mean backend, data science, or automation. Copilot understands these relationships, but you should too for conversations.
3
Assessing Seniority Levels
Junior: 0-2 years, learning fundamentals. Mid: 2-5 years, independent work. Senior: 5-10 years, technical leadership. Staff/Principal: 10+ years, architecture and strategy. Look at: years of experience, progression speed, scope of impact, and titles. Be cautious of title inflation.
4
Reading Technical Resumes
Focus on: technologies used (not just listed), project scope and impact, progression and growth, and specific contributions. Red flags: technology laundry lists without context, gaps without explanation, titles that don't match experience. Green flags: specific achievements, open source contributions, and clear technical progression.
5
Speaking with Technical Candidates
You don't need to be technical, but you need to be credible. Know the basics of the role's tech stack. Ask about projects and contributions, not just skills. Let them explain technical concepts - good engineers can do this. Don't pretend to understand when you don't.
Key Takeaways
- Learn the basic layers: frontend, backend, database, cloud, devops
- Understand skill relationships (React → JavaScript, AWS → Cloud)
- Assess seniority by impact and progression, not just years
- Read for context and achievements, not just skill lists
- Be credible but honest about your technical knowledge
