The Real Fix for Bad Sales Hires Isn't a Longer Interview Process
By Anton Menkveld · 24 July 2026

Key takeaways
- More interview rounds just repeat the same room-performance problem
- Profile the role first, then profile every candidate against it
- Individualised interview guides target each candidate's specific risk areas
- Automated reference checks confirm or challenge exactly what the profile flagged
- One ongoing fit score built from real data, not gut feel
When a slick interview performance hides more than it reveals, what's the actual fix? A longer interview process, more rounds, more people involved? Getting your best rep into it? Both have real appeal, and both come with a cost worth understanding before you pick one.
The two obvious fixes don't hold up
More rounds just gets you more of the same signal in more rooms, someone performing on their best behaviour for a different audience each time, while adding real weeks to a hiring process that's already forty-five to sixty-five days long.
Putting your best rep in the room is closer to right. They'll spot gaps a generalist hiring manager misses. But what they're applying is still their own instinct, shaped by their own way of selling, to a candidate they've just met. It's a better-informed gut read than most, but it doesn't scale past that one person, and it rarely comes with criteria anyone else could pick up and use.
| Approach | What it actually fixes | Where it still falls short |
|---|---|---|
| Longer interview process (more rounds) | More chances to catch inconsistencies across separate conversations, with different people | Still measuring performance in the room each time, just in more rooms. Costs you weeks in an already slow process. |
| Best rep sits in | A genuinely informed read, better than a generalist hiring manager's | Still one person's gut instinct. Doesn't scale past that person, and rarely comes with criteria they can name. |
Here's what we built instead of picking one of those two.
How GrowMyTeam actually closes the gap
The short version is that we replace a single subjective read with a system that measures the same thing at every stage, from before a resume lands to after the reference call.
1. A profile of the role before a profile of anyone
Every role gets its own ideal-candidate DISC profile first (a structured behavioural style assessment), built through our job profiling process. Before a single application comes in, you already know the behavioural pattern that predicts success in that specific seat, not sales in general.
2. Candidates get profiled before they get interviewed
Every candidate completes a DISC profile before the interview stage. Their behavioural pattern is on the table before they've said a word to you, well before the room where a good talker can shape the read.
3. Interview guides built for the person in front of you
The gap between a candidate's profile and the ideal one for the role feeds directly into an individualised interview guide, questions written to probe the specific areas where that candidate's pattern diverges from what the role needs. Two candidates for the same role can end up with genuinely different questions, because they're carrying different risk.
4. Reference checks that chase the same risk areas
Those same risk areas carry through to an automated reference check, targeted questions sent to the specific referees best placed to confirm or challenge what the profile flagged, rather than a generic checklist every referee gets regardless of what's actually in question.
5. One score built from all of it
The role profile, the candidate's DISC result, the interview guide outcomes, the reference responses, and more, all roll up into an ongoing, multi-point fit score. It's a score assembled from what was actually measured at every stage, not a gut feel dressed up as a number after the fact.
