Data engineer recruitmentClients in the UK, Europe and USA

The CV says BigQuery. It can’t tell you what happens on a replay.

Data engineering CVs are lists of tools. A data engineer reads every one before you do and tests what matters: duplicates, late events, partial failure and data quality.

Where your hiring time goes

01

The re-screening tax

A recruiter can match BigQuery or Dataflow to a job spec. They can’t tell whether the candidate has kept a pipeline idempotent or caught bad data before it reached a report. So you re-read every CV, and weak candidates still reach your interview.

02

The CV stopped being evidence

The CV saysBigQuery, Dataflow, Pub/Sub
It can’t tell youWhether they can explain ordering, duplication and replay in an event-driven pipeline, and keep BigQuery cost under control.
The CV saysPostgreSQL, MongoDB
It can’t tell youHow access patterns and retention should change partitioning, indexing and storage design.
The CV saysTemporal, Big Data
It can’t tell youHow their pipelines recover from partial failure and surface bad data before it reaches downstream products.

If you run hiring for engineering

You need CVs that pass engineering’s interview, so you can send a shortlist it trusts. An engineer reads every CV before it reaches you. Fewer CVs, but better ones.

58%

of HR and recruitment leads who use agencies say the main reason engineering rejects agency candidates is that the CV looked good, but the person couldn’t do the job.

What the CV can’t tell you, and our interview does

A developer or CTO who works in the stack interviews every candidate. Each of these is a question you would otherwise only answer in your own interview.

Pipeline design

Whether they can choose batch or streaming components, control cost and explain ordering, duplication and replay behaviour.

Storage decisions

How they handle data modelling, partitioning, indexing and consistency, and how access patterns and retention change the design.

Failure and data quality

How their pipelines recover from partial failure, stay idempotent and expose data quality problems before incorrect records reach downstream products.

What every shortlisted candidate has to show

Knows what the data platform is doing

They can explain what the warehouse, queue or orchestrator does underneath, and investigate a surprising number instead of patching the symptom.

Uses AI with engineering discipline

They can explain how they check generated SQL and pipeline code, and keep personal and confidential data out of AI tools.

Honest about uncertainty

They tell colleagues what the data can and cannot show, and say plainly what they have not worked with before.

How we take the screening off your desk

We recruit data engineers for ingestion, transformation, storage and event-driven systems. A data engineer screens every candidate on pipeline design, SQL and NoSQL trade-offs, cloud data services, observability and how distributed data workflows behave in production.

Either way you get about 3 to 5 screened CVs a week, per role.

Route 1: we screen, you run the deep interview

We do

  • Source candidates for the role
  • A technical screen of every candidate, run by a developer or CTO who works in your stack
  • A CTO approves every CV before it reaches you

You do

  • Run the deep technical interview with the shortlist
  • Make the offer

Route 2: we run the deep interview too

We do

  • Everything in Route 1, including the technical screen of every candidate
  • A 1.5 to 2 hour live-coding, architecture and implementation interview with your final candidates
  • A written assessment of each candidate after the interview

You do

  • Meet the candidates who passed
  • Make the offer

What clients say

“Metamindz helped us recruit our now CTO, reviewing CVs as they came in and then putting the CTO through a thorough 90-minute live 360 technical test. Feedback from our now CTO of the test was glowing and comms from Metamindz throughout the entire process were excellent. Highly recommend!”

Rupert Boddington

Co-Founder, Pockla

“Worked with Lev and Max. We worked with MetaMindz to help us interview and assess software engineering candidates. They were professional and great from the outset and throughout, great speed too. Would 100% recommend and we will be working with them again.”

Alexander Bushe

CEO, Fuller Focus

“We found it really easy working with Lev and the team to hire for our lead developer role and despite it still being early days, our new hire is making an impact already!” source
