TECHNICAL COMPETENCY

FRAMEWORKS AT WORK

A Ready to Use Handbook for Implementing Technical

Competency Frameworks in Organizations Along with
Interview Questions
Introduction
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.

Hiring decisions cast a long-lasting impact on the

company’s productivity, attrition and success rate.
Hence, recruiting candidates for different technical roles
becomes a roadblock for many because every job role
requires a different set of technical competencies
against which a candidate should be measured.

However, to solve all your woes, Mettl has come up with

a process that helps in on-boarding a smart technical
recruit. The three vital aspects that lay a strong founda-
tion of a stellar hiring spree are- Competency Frame-
works, 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 frame-
work handbook covering eight popular job families. This
would in turn benefit organizations in making the right
technical hires.

Because,

Mettl Helps Organizations Build

Winning Teams.

90% of Fortune 500 companies use Java as a
server-side language for back-end development. It is
in demand in the finance sector specially in E-com-
merce websites. Future scope of Java programmers in
India is great since Java emerges as the most widely
used programming language worldwide. With
government’s Digital India initiative and demonetiza-
