Emumba cut time to hire from 7 weeks to 3 with InterWiz

Emumba is a software services company that partners with startups and enterprises to design, build, and scale software products. Its teams work closely with customers, often embedding within client-facing delivery teams to ship and support production systems.

Emumba employs 350+ engineers across multiple geographies and hires approximately 80 engineers globally each year across engineering and business functions.

Because new hires are typically deployed directly into active delivery teams, hiring quality is critical. At the same time, delivery commitments leave little room for slow or fragmented hiring processes, making speed, consistency, and decision confidence equally important.

We were spending more time scheduling and repeating the same first-round interviews than actually evaluating candidates. By the time we reached good applicants, they had already accepted other offers.

As Emumba’s hiring volume increased, pressure began to build in the interview stage of the hiring process.

On average, time to hire was close to seven weeks per role. While sourcing was not the primary issue, progress slowed once candidates entered interviews, affecting team ramp-up and delivery planning.

There was also a lack of consistency in interviews and feedback. Interview approaches varied across teams and interviewers, and feedback was not always detailed or structured, making it difficult to compare candidates objectively and make confident early decisions.

Emumba needed a hiring process that could move faster, reduce dependency on senior engineer availability, and produce clear, comparable signals for every candidate.

To resolve these issues, Emumba introduced InterWiz as a replacement for manual screening interviews and the first in-depth technical interview.

InterWiz was rolled out gradually, starting with frontend engineering roles, and then expanding across backend, DevOps, QA, HR, and business functions such as Marketing. This phased approach allowed teams to adopt the platform within their existing hiring workflows, without disrupting ongoing recruitment.

To make the experience seamless, Emumba also adopted a two-way integration with its ATS, PinPoint.

By replacing manual screening with structured, AI-powered assessments, Emumba reduced its time to hire from approximately seven weeks to three weeks, a 60% reduction without sacrificing evaluation depth or consistency.

Standardized evaluation reports across roles and teams.

InterWiz has made our hiring process super simple and automated. We’ve cut our time to hire by 60%, and the platform helps us make fair and informed decisions. It’s been a game-changer for us.

Building on these results, Emumba plans to extend its use of InterWiz to initial phone-based AI screenings across all roles.

This next step will standardize the very first stage of hiring, ensuring early signals are captured consistently before candidates move further into the process.

The focus going forward is to keep hiring fast, consistent, and predictable, without increasing operational load as hiring volumes grow.
