An engineering hiring process works better at 4 rounds than 9.
Cut it to 4. A screen, practical coding, a depth round, a hiring manager conversation.
Run it in 1 day so the panel meets while the memory is fresh.

Require every scorecard submitted before anyone speaks in the debrief.
A typical engineering hiring process runs 7 to 9 interviews over a month.
A 9-interview hiring process still produces decisions the panel cannot explain a week later.
3 changes do most of the work.
Change 1: why cut the hiring process to 4 rounds?
Seven rounds mostly re-measure the same signal, with tired people doing the measuring.
Four cover it. A 30-minute screen. A 60-minute practical round from your own codebase.
A 60-minute depth or design round. A 45-minute hiring manager conversation.
A fifth round adds noise.
| Round | Length | What the round measures |
|---|---|---|
| 1. Screen | 30 minutes | Experience, motivation, level. Does this person want this job or any job? |
| 2. Practical coding | 60 minutes | A problem from the actual codebase, stripped down |
| 3. System or technical depth | 60 minutes | One design problem with clear constraints, scored against criteria written in advance |
| 4. Hiring manager and team fit | 45 minutes | How they work with people and handle disagreement, and what they need from a manager |
The practical coding round allows AI, documentation, whatever the candidate uses at work.
You are hiring the person who will work that way on Monday.
Change 2: why run the hiring process in 1 day?
A hiring process spread over 3 weeks loses candidates to companies that decided faster.
One day, on site or remote, with breaks, and the panel meets the same afternoon.
The work an 80,000 euro engineer would do is worth at least their salary. That is about 300 euro a working day.
3 extra weeks of hiring process is not free.
The cost is coordination.
You stop losing the people you wanted. Your engineers spend fewer hours in total.
Nobody re-reads notes from 12 days ago.
Change 3: why do scorecards have to come before the debrief?
Scorecards come before the debrief because the first opinion spoken sets an anchor.
The rest of the panel drifts toward it.
Every interviewer submits score and evidence before anyone speaks, the most senior person included.
The debrief then examines disagreement rather than averaging it away.
The scorecard rule is the change with the highest return and the lowest cost.
What a shorter hiring process does to the numbers
Structured interviews have a validity of about 0.42 against job performance.
Unstructured ones have about 0.19 (Sackett and colleagues, 2022).
Cutting 5 rounds saves about 15 engineering hours per candidate. That assumes 2 interviewers and 90 minutes a round.
Multiply it by every candidate who reaches the final rounds.
You get better decisions and the saving comes along with it.
Should candidates use AI in the coding round?
Candidates should use AI in the coding round, on a task that requires it.
Watch what they ask, what they accept unchecked and how they validate the output.
An engineer who prompts carelessly and ships the result is a real risk. AI makes that risk observable.
Watching someone use AI is a far stronger signal than a binary search from memory.
Time spent trying to catch candidates using AI is time not spent designing that task.
What do most teams get wrong when they change the process?
Teams change the hiring process without changing the interviewers.
Robert Walters research found 40% of hiring managers never had formal interview training.
Being a strong engineer does not make someone a strong interviewer.
Shorten the hiring process without calibrating the panel and you have made it faster.
Where to start
Pick 1 change. The scorecard rule is free and you can apply it to the next debrief.
Look at the length of the hiring process next, then at interviewer training.
Measure one number before you change anything. Days from first contact to offer.
Every change here moves it, and it is the one candidates feel.
Want the whole hiring process rebuilt rather than patched? That is the work I do here.

Common questions
Can 4 rounds really assess a staff-level candidate?
Yes, with the depth round scoped differently. At staff you use the same 4 slots and change what each looks for. Ambiguity handling, choosing what not to build, influence without authority. Adding a fifth round usually means the panel has not agreed what staff means here.
Is a full day of interviews fair to candidates?
A full day of interviews is usually fairer than 3 weeks of evening calls. Give real breaks. Tell them the schedule in advance. Pay for the travel. Candidates who prepare properly handle a single day better than the fragmented version. That one wastes more of their time.
What is a hiring process?
A hiring process is the ordered set of rounds a company runs before an offer. A good one names what each round measures and who decides. Long processes spread rounds over weeks and re-measure the same signal. Four rounds in one day cover it.
Which of the 3 changes should you do first?
Start with written scorecards before the debrief. It is free and needs no scheduling. You can apply it to the next debrief on your calendar. Changing the hiring process length needs coordination, and interviewer training needs budget. Start with the one that costs nothing and shows an effect in one meeting.
What do you do when the panel cannot agree after the debrief?
When the panel cannot agree, go back to the evidence rather than to the room. Ask each interviewer which scorecard line they scored and what the candidate actually said. Disagreement about evidence is resolvable in minutes. Disagreement about a feeling is not. Treat that one as a no.
The short version
The faster hiring process: 4 rounds, 1 day, scorecards submitted before anyone talks.
Train the interviewers or the rest is decoration.

When a Take-Home Assignment Works
A take-home costs a candidate a weekend and costs you the ones with children. Here is when it is worth asking.
Want this fixed in your loop?
SmartHiring trains engineering interview panels on their own open roles. Elman Huseynov, a Tech Hiring Expert in Berlin, runs every engagement. One workshop writes the scorecards for your roles, then calibration runs until the panel agrees. It starts with a free 30-minute call.
No pitch if the loop is already fine. See an example audit report.
