Signal-to-selection ratio measures how much information HR teams gather about a candidate versus how much they truly use while making a hiring decision. A high ratio means recruiters are collecting a lot of data through interviews, assessments, references, and work samples, but are only using a fraction of it. On the other hand, a low ratio means the process is lean, focused, and decisive.
When an organisation’s signal-to-selection ratio is bloated, they are asking employees for information that is not going to be used while making a decision, exhausting hiring managers by having them go through this unnecessary pile of information, while still making unfit hires. The solution is simple: spot the signs of this bloated system early and streamline it by asking only the relevant information from the candidates.
What are the signs to spot a high signal-to-selection ratio?
A high signal-to-selection ratio reveals itself in the gap between your hiring process and your actual decision-making.
- Endless rounds with no clear purpose: Candidates are called for multiple rounds of interviews and are asked the same questions over and over again. If the same information is being collected in each round, then it’s a case of unclear process.
- Reference checks are not a factor: While most HR teams collect references from the candidates, very few of them actually follow up on that. Even when they do, reference feedback is rarely the decisive factor in deciding whether to hire the candidate or not. This is another piece of unnecessary information that slows down the process.
- Culture fit or gut feeling: After days and weeks of a structured process, many recruiters make the final decision about the candidate based on gut feeling and culture fit. These are subjective impressions, which are usually formed in the first meeting with the candidate. Hence, the recruiting team unnecessarily wasted time and resources on a decision they had already made on the first day.
How to optimise your signal-to-selection ratio?
Reducing your signal-to-selection ratio means auditing what organisations measure and why. HR teams must list every step in the assessment process, screenings, interviews, and references ad identify what specific decision criterion it informs.
- Eliminate redundant interview rounds: If three interviewers are all assessing the same qualities in the candidate, cut them down or assign each interviewer to measure a distinct quality so as to avoid any overlap.
- Use relevant assessments: If recruiters give a relatively easy assessment to all the candidates, it becomes difficult to choose between an average candidate and a strong candidate. The organisation will then have to design another round of assessment, thus giving additional work to the recruiters.
- Make reference checks count: HR teams must either use references to validate specific concerns or capabilities, or admit they're not influencing decisions and drop them and save time.
What are the common mistakes that inflate the signal-to-selection ratio?
HR teams often fall into the trap that a bloated hiring process is equivalent to improved hiring outcomes. That’s not the case most of the time. Designing a streamlined, direct and straightforward hiring process saves time and money for the organisation.
- Adding steps to look more rigorous: Candidates and stakeholders might be impressed by a lengthy process, but if those steps don't improve decisions, all that time invested is a waste.
- Repeating the same steps: Legacy processes accumulate over time. Recruiters added a step a few years ago for a reason that no longer applies, but no one has questioned it since. The result is that the recruiting team is following a process that no longer serves any purpose.
- Anxiety drives over-collection of data: When recruiters are hiring for a high-profile role, the instinct is to collect as much information about them as possible. But too much information makes it difficult to recognise which one is actually important for the role. The trick here is to keep a check on the instinct and focus on the information crucial for the role.
Conclusion
Signal-to-selection ratio ensures that the process respects the time and effort of the hiring team, candidates and the team managers. Every step in the hiring process should be well thought through and should contribute towards improved decision-making. If that’s not the case, then the system is unnecessarily bloated.
Recruiters must understand that building an intensive and time-consuming process does not equate to impressive hiring. The focus should be on making the process simpler, straightforward, quick and effective. Collect data that is actually going to be put to use, or your systems will be filled with unnecessary paperwork that no recruiter’s going to ever need!
