Technical Competencies At Work

A Ready to Use Handbook for Implementing Technical Competency Frameworks in Organizations Along with Interview Questions



Technical hiring remains at the core of every business venture since technical expertise is what holds the basic organizational framework together. Which is why recruiters and hiring managers are always looking for niche talent who would adhere to the company’s work culture and align with the vision to give quality output.

The three vital aspects that lay a strong foundation of a stellar hiring spree are- Competency Frameworks, Technical Screening Questions, and Telephonic Interview Questions. To strike a balance between the three and based on our experience of working with 2,000+ clients, we have compiled a ready to use technical competency framework handbook covering eight popular job families. This would in turn benefit organizations in making the right technical hires.
