A job interview is not just you, as a recruiter or hiring manager, evaluating a candidate. While you’re assessing a developer’s technical and soft skills, they’re noticing everything — even your laptop stickers and outfit can reveal something about the company culture. They pay even more attention to things such as Wi-Fi speed and leadership vibes.
Here are five things developers secretly judge during your interview process.
1. The Wi-Fi situation
If your video call freezes three times during a discussion of backend architecture, the candidate is taking notes.
Developers assume your infrastructure reflects your standards. If the basics don’t work smoothly, they wonder what production looks like.
2. The office vibe
How is the office like? Open space? Silent and tense? Loud and chaotic?
Are people looking healthy or miserable?
Developers notice whether and how engineers talk to each other, if people are looking relaxed or tense, and how managers interact with the team.

3. The tech stack — and how you talk about it
Don’t worry, experienced candidates know that no system is perfect. Talking openly about your stack, including its limitations, builds trust. When you openly acknowledge the trade-offs you’ve made, you signal maturity and strong engineering culture.
4. The hardware reality
Does it sound shallow? Well, it isn’t. A laptop is a developer’s primary tool. If the tool is slow, outdated, or non-negotiable, it will directly impact their output. Good equipment, including a second and even third screen, can be just as important to a developer as the number of vacation weeks they get.
5. The small details
No, it’s not about offering gourmet coffee.
But things like decent coffee, comfortable chairs, a fridge with drinks, a pool table, and proper monitors make a difference in their workday. It’s about care and consideration.
Bonus
Developers know when the questions you ask are relevant and when they are just copied from Google. They notice if you’ve read their CV carefully or not. They pay attention to whether you show up on time or not, and to whether you are engaged and attentive or not.
Remember, an interview is a preview of your company’s standards and work style. When candidates leave an interview feeling respected, challenged, and inspired, they are far more likely to accept an offer — and even if they don’t, they become ambassadors for your brand.
Treat each interview as an opportunity to demonstrate excellence, and you’ll naturally attract excellence in return.
