A candidate who isn't prepared doesn't perform like they would on the job. If your technical interview is meant to measure someone's real skills, and not just how they handle surprise and stress, you need to prepare them for it before they ever join the call.
Here's what we've learned actually works, after running thousands of technical interviews on behalf of our clients.
Tell Candidates What to Expect, in Writing
Send a short email a few days before the call. Candidates who know what's coming spend their energy on the actual questions, not on guessing the format. Cover:
- How long the interview will run
- The format: video call, shared IDE, whiteboard, or a mix
- How many interviewers will be on the call
- The broad topics or tech stack that will be covered
- Whether AI tools or internet searches are allowed
- What, if anything, they should bring or set up beforehand
Share the Interview Structure
Every AssessDev interview follows the same three part structure: a short intro, a set of technical questions, and a hands on challenge. We publish that structure openly, because removing surprise doesn't lower the bar. It just removes noise that has nothing to do with the candidate's actual skill.
If you run your own interviews, do the same. Point candidates to a sample structure, like our sample tech assessment interview structure, or write your own one page guide. Candidates who know the shape of the interview can focus on showing their thinking instead of decoding your process in real time.
Give a Realistic Sample Question
One carefully chosen example question, shared in advance, does more to calm nerves than any reassurance you can offer live. It shows candidates the level of depth you expect and the style of question you ask, so their first real question isn't also their first surprise.
Example: "Name the application servers you know for your primary stack, and explain the biggest differences between them."
Confirm Logistics 24 Hours Before
A confirmation message the day before, covering time zone, meeting link, who's attending, and a way to reach someone if there's a technical hiccup, prevents the kind of stress that shows up at the last moment and has nothing to do with technical ability but still affects performance.
Offer a Short Prep Call for Senior or Leadership Roles
For CTO, tech lead, or other leadership hires, a brief 15 minute prep call goes a long way. It gives the candidate a chance to ask logistical questions, and gives you a chance to set expectations for a more open, architecture focused conversation.
Debrief Candidates Afterwards
Whether or not they move forward, candidates remember how they were treated. Structured, specific feedback, covering what they did well and where they could improve, turns even a rejection into a positive experience, and strengthens your reputation with every candidate you interview.
The Payoff
Prepared candidates perform closer to their real ability, drop out less often, and walk away with a better impression of your company, even when they don't get the offer. None of this requires lowering your bar. It just means removing the parts of the process that measure how well someone copes with the unknown, instead of how well they can do the job.
