Google’s algorithm-powered inside job market


Google’s frontline groups wanted a brand new staffing mannequin to higher assist technique shifts and worker growth. It wanted to be scalable and dynamic, so we created a job market, giving staff and managers decisions.

gTech is a assist and operations group and inside gTech the Customers and Merchandise division works to make sure customers and companions get essentially the most out of Google. For a very long time, the staff was organized round particular person merchandise however at any time when Merchandise methods shifted (a frequent prevalence in tech) we would want to reassign sources shortly. The previous mannequin wasn’t agile sufficient to shortly assemble groups with the right combination of technical and operational expertise. In the meantime, we knew from our worker engagement survey that groups wished extra growth alternatives, profession mobility, and information sharing.

We thought of hiring buffer capability (too costly), rotation applications (too inflexible), and attempting to evangelize our current inside job board (too gradual) and dominated all of them out. We wanted a scalable and dynamic staffing mannequin. Working with an in-house economist, we determined to check a market method the place staff and managers “bid” for assignments.

However the satan was within the particulars. How would we really make this work for a corporation of a whole lot of individuals? How would we prioritize initiatives? How would we get the proper talent match between worker and function? How would we stop folks from gaming the system? How would we all know if this system was profitable?

We wish to supply actual option to staff. This meant we would have liked to create a market that was “thick” sufficient with a essential mass of various alternatives. We settled on batching job postings in three rounds a yr. The concept was to get staff and managers to be much less possessive of initiatives or groups. We wanted staff to maneuver round extra, adapting to their environment, so we known as the hassle “Challenge Chameleon.”

We additionally needed to construct a platform for this market. To assist nudge staff and managers to think about talent match, the device displayed a color-coded match rating based mostly on the overlap between the Googler’s experiences and the job’s necessities. Googlers and managers ranked their preferences and we paired them utilizing a Gale-Shapley Deferred Acceptance Algorithm. The algorithm would match staff to roles based mostly on their preferences and people of the supervisor. The same method has been used for many years within the US to match tens of hundreds of graduating docs with hospitals.

We mentioned operating a small pilot, however the market required a essential mass of jobs, so we launched with rolling enrollment, posting a couple of third of all positions every spherical in order that after the primary yr, all roles can be in Challenge Chameleon.

Constructing belief within the market and matching was robust, despite the fact that Google is a spot constructed on algorithms. We wanted everybody to record their true preferences for Challenge Chameleon to work. It was a gradual begin, with solely 11% of staff really shifting within the first spherical; of those who moved, greater than 25% didn’t get their best choice. And whereas we by no means intervened with the algorithm’s output, we might speak with a Googler in the event that they matched with a really low-ranked job to see if there have been nonetheless different roles they’d reasonably pursue. By the second yr, extra Googlers switched roles in a single batch than had switched in all of the prior rounds. At this level, our information confirmed that Googlers trusted the market with 74% agreeing in an nameless survey that “I felt comfy sharing my true preferences” (and solely 5% disagreed).

This system has been operating for a number of years now and whereas there have been loads of tweaks alongside the way in which (like eliminating a spherical in the course of the hectic fourth quarter) we’re seeing a few of our supposed outcomes:

  1. Prioritization – The brand new enterprise prioritization course of on the group stage, reasonably than by product, offered worthwhile insights throughout the management staff and helped everybody assume much less defensively about their groups and extra expansively about Google’s strategic alternatives.
  2. Transparency – Publishing all challenge roles and required expertise offered transparency to Googlers of all obtainable alternatives.
  3. Agility – Launching centralized, steady hiring for the Chameleon-eligible roles along with this system added agility to the resourcing mannequin. New hires, who didn’t know sufficient to make knowledgeable bids, had been assigned after {the marketplace} had matched everybody else.
  4. Alternative – After six rounds of this system, Googlers and managers received one in all their high three decisions 90% of the time. Extra individuals are shifting round and 80% of staff and managers report they’re glad with the method.

There have been additionally some unintended advantages. We discovered that Chameleon normalized motion within the group, making it extra comfy for Googlers to speak with their managers about profession growth. This system additionally facilitated networking as Googlers reached out to managers to study extra in regards to the alternatives obtainable. We even created an entire tradition across the program; “Chameleon” has really turn into a verb within the group. For instance, you may hear: “The Product staff wants somebody on this new launch, can we Chameleon that?”
As we take into consideration sharing our classes with groups throughout Google and past, right here’s what we discovered is required to make the Chameleon mannequin work:

  • Dedication from management and execution groups
  • Workers with transferable expertise in search of growth alternatives
  • Substantial quantity of jobs that require generalist expertise
  • Inclusive design and implementation method
  • Program administration with a deal with folks growth, organizational design and alter administration
