Hiring salespeople for a technical or complex product

How to hire salespeople for DeepTech, engineering-led and technically complex products: what technical credibility actually means, how to test it, and what not to over-index on.

The short answer

Technical credibility in a seller means being able to hold an honest conversation with a technical buyer, know the limits of their own knowledge and bring in the right colleague without losing control of the deal. It rarely means a relevant degree, though the bar depends on who your buyers are: where an evaluation is run by engineers, the bar is higher than where it is run by a commercial team. Test it with a live conversation about your actual product, and test commercial skill separately — the frequent failure is hiring someone who can discuss the technology fluently and has never run a buying process.

What technical credibility actually is

For a technical buyer, credibility is not vocabulary. It is whether the seller can explain what the product does and does not do, follow a technical objection without deflecting, and say plainly when they need to bring in an engineer. A seller who bluffs is discovered in one call and the account is usually finished.

That is a testable skill rather than a qualification. Some of the strongest technical sellers came from support, implementation or engineering; others have no technical background and simply refuse to pretend.

The two-test interview

  1. 01Run a technical conversation: give the candidate your real product material in advance and have a technical colleague hold a genuine discussion, including something the product cannot do.
  2. 02Score honesty and structure, not fluency: did they establish what the buyer was trying to achieve, and did they say when they did not know?
  3. 03Run a separate commercial exercise: how they would qualify, who else they would need to meet, and what would make them walk away.
  4. 04Compare the two scores deliberately. Strength in one does not compensate for absence in the other.

What not to over-index on

  • A degree in your field, unless your buyers genuinely require it as a condition of the conversation.
  • Competitor experience, which buys a network and can also buy transferred bad habits.
  • Fluency with the terminology, which is learnable and often masks the absence of commercial process.
  • Long enterprise logos on a CV, if your evaluations are run with small technical teams instead.

Support the hire, or the hire will fail

A complex product sale usually needs somebody technical in the room at some point. If the only person able to do that is a founder or an engineer with a delivery deadline, the seller will either stall deals or start answering questions they should not be answering.

Decide in advance who supports demos and technical evaluation, and how that time is protected. If the answer is nobody, the honest brief is for a more senior generalist who can carry more of it alone — and the process should test that specifically.

How this maps to the Adroit screening process

Our five-stage screening exists for exactly this split: technical understanding and human selling skill are assessed as two separate tests rather than one impression, and we tell you which of the two a candidate is stronger in rather than presenting a single verdict.

Common questions

Should we hire an engineer and teach them to sell?
Occasionally it works, particularly for a first commercial hire in a very technical field. Be clear that you are then teaching commercial process from scratch, which needs someone to teach it — usually the founder, deliberately, for a sustained period.
Do we need a solutions engineer before a second seller?
Often yes, if technical support is currently the bottleneck rather than pipeline. It is worth checking which constraint is real before adding another quota.
How do we test technical credibility without a technical interviewer?
Use a real customer question you have already answered and compare the candidate's handling with what actually worked. It is not a substitute for a technical colleague, but it does expose bluffing.
