5 common mistakes companies make when hiring IT talent

Most companies believe hiring IT talent is hard because there aren’t enough good developers. The market is competitive, salaries are climbing, and strong candidates are snapped up quickly. That much is true.

But in our experience working with dozens of companies across Europe and beyond — from early-stage startups to established tech teams — the bigger problem is almost never the talent market. It’s the hiring process itself.

Time and again, we watch qualified candidates disengage, decline offers, or disappear entirely — not because a better opportunity appeared, but because the company got in its own way. Slow responses. Vague job descriptions. No thought given to what happens after the contract is signed.

The good news: these are all fixable. None of them require a bigger budget or a larger HR team. They require clarity, discipline, and an honest look at where your process is leaking.

Here are the five mistakes we see most often, and exactly what to do about each one.

Mistake #1: Writing a job description that scares away good candidates

The job description is the first thing a candidate reads about your company. It sets the tone for the entire relationship — before a single conversation has happened.

Most companies write job descriptions as internal wishlists. They list every technology the team has ever touched, demand five years of experience for roles that don’t actually need it, and bury the interesting parts (the team, the problem, the product) under a wall of requirements.

The result is predictable: strong candidates who could do the job well see three dealbreakers in the first paragraph and move on. Only those with nothing to lose apply.

What this looks like in practice

We recently reviewed a job description for a mid-level backend developer role. The requirements section listed 14 technologies, including three that the team admitted were “nice to have”. The salary range wasn’t mentioned. The description of the actual work was two sentences long. The company had been running that vacancy for nine weeks.

Meanwhile, a competitor with a cleaner, more honest JD for a similar role filled it in three.

How to fix it

• Separate must-haves from nice-to-haves, and be ruthless about the must-have list. If your team can train someone on a technology in a month, it’s not a requirement.
• Lead with the work, not the credentials. What will this person actually build? What problem are they solving? Who will they work with?
• Include a salary range or at least a band. Candidates who ask about compensation aren’t mercenary — they’re efficient. Withholding the range wastes everyone’s time.
• Have a senior engineer review the JD before it’s published. HR writes the structure; engineering confirms it reflects reality.
• Keep it under 600 words. If you can’t summarise the role in 600 words, the role itself may need defining first.

Mistake #2: Running a slow, multi-stage hiring process

Developers in Belarus and across Central and Eastern Europe know their market value. A senior engineer who decides to explore opportunities on a Monday will typically have two or three conversations scheduled by Wednesday and a first offer in hand within ten days.

Your five-round interview process with a committee decision and a three-week deliberation period is not operating in that reality.

The cost of slowness

Slow hiring doesn’t just mean losing a specific candidate. It means the candidates you do attract are disproportionately those who couldn’t get an offer elsewhere, or who have accepted a counter-offer by the time you’re ready to move. It systematically selects against your best options.

One of our clients lost three strong candidates in a row before we audited their process together. Their average time from first interview to offer was 31 days. The market average for the roles they were hiring was 11. No amount of employer branding could compensate for that gap.

How to fix it

• Cap your process at three stages: a screening call, a technical interview, and a final conversation or offer. Anything beyond that requires strong justification.
• Set internal SLAs. No more than three business days between stages. Put this in writing and make someone accountable for it.
• Designate a single decision-maker for each hire. Committees are slow, and they dilute accountability. One person owns the hire; others provide input.
• Prepare your technical assessment in advance. Candidates should never wait a week for someone to write a coding task.
• Make the offer verbally before the written contract is drafted. A fast verbal offer keeps momentum while paperwork catches up.

Mistake #3: Evaluating only technical skills and ignoring how people work

Technical skill is necessary. It is not sufficient.

A developer who can’t communicate what they’re working on, who shuts down in code reviews, or who needs every task broken into sub-tasks will cost you far more than a slightly slower technical hire who communicates well, asks good questions, and makes the people around them better.

Companies that hire purely on technical merit discover this at around the three-month mark, by which point the cost of a bad hire — in time, morale, and re-hiring — is already significant.

What “team fit” actually means

We want to be precise here, because “culture fit” has been misused as cover for bias often enough that it deserves scrutiny. We’re not talking about personality type, background, or whether someone will fit in at team drinks.

We’re talking about working style: how someone handles ambiguity, how they give and receive feedback, how they behave when a project is behind schedule, whether they default to asking for help or silently struggling. These things can be evaluated systematically and objectively.

How to fix it

• Add one structured behavioural interview to every hiring process. Use STAR-format questions: Situation, Task, Action, Result.
• Focus on scenarios that map to how your team actually works. If your team does a lot of async communication, ask about that specifically. If you have a high-feedback culture, ask about a time they received difficult feedback.
• Involve a future peer, not just a manager, in at least one stage. Managers evaluate output; peers evaluate working dynamics.
• Write down what “good fit” means for this specific team before the process starts. If you can’t define it in advance, you’re making it up as you go.

Five behavioural questions worth adding to your process:

• Tell me about a time you disagreed with a technical decision that was made above you. What did you do?
• Describe a project that didn’t go the way you planned. What happened and what did you learn?
• How do you typically communicate progress to non-technical stakeholders?
• Tell me about a time you had to work with incomplete requirements. How did you approach it?
• What does a good code review look like to you, both giving and receiving?

Mistake #4: Treating the offer as the finish line

The offer is accepted. You exhale. The hiring process is over.

Except it isn’t. The hiring process ends at the 90-day mark, at the earliest. Everything between the signed offer and a confident, productive team member is still your responsibility — and it’s where a surprising number of companies lose people they fought hard to recruit.

The first week matters more than most companies realise

Research consistently shows that new hires form a strong opinion about their decision within the first five working days. By the end of week one, most of them know whether they made the right choice. If their laptop arrived late, their access credentials took three days to sort out, their manager was unreachable, and they spent day one reading outdated documentation alone in a corner — that impression is very hard to reverse.

We’ve seen candidates who were genuinely excited about a role hand in notice during their probation period because the onboarding experience felt like no one had prepared for them. The recruitment was excellent; the welcome was an afterthought.

How to fix it

• Build a Day 1 checklist and assign ownership. Equipment, credentials, system access, calendar invites for the first week — all prepared before the start date.
• Assign a buddy, separate from the direct manager. Someone the new hire can ask “silly” questions without worrying about how it looks.
• Schedule structured check-ins at day 7, day 30, and day 90. These are not performance reviews. They’re conversations: how’s it going, what’s confusing, what would help.
• Give new hires something meaningful to do in week one. A small, well-scoped task that lets them contribute and orient themselves in the codebase is worth more than a week of reading.
• Have the manager proactively introduce the new hire to the team — one-to-one conversations, not just a Slack announcement.

Mistake #5: Using the same process for every role

The process that works well for hiring a junior frontend developer is not the process that works for hiring a CTO. Using the same framework for both — the same screening questions, the same interview stages, the same offer template, the same 90-day onboarding plan — signals to senior candidates that you haven’t thought carefully about what they actually need.

Senior and executive hires evaluate companies as much as companies evaluate them. They’re paying close attention to how the process is run, what questions are asked, and whether the people they meet seem to understand what the role requires. A generic process reads as a lack of seriousness.

Three hiring tracks worth defining

Junior and mid-level IC roles. Faster process, practical coding assessment, emphasis on learning orientation and communication. These hires have the most room to grow into the role, so you’re partly betting on trajectory.

Senior and lead IC roles. Shorter process (they have less patience for unnecessary rounds), system design conversation instead of a coding screen, one behavioural interview focused on working across teams. These candidates can smell a poorly-run process immediately.

Management and executive roles. Significantly different process: longer conversations about vision and decision-making, structured reference calls, a trial project or working session where appropriate. The criteria shift from “can you build this?” to “can you build the team that builds this?”

The investment in building three separate playbooks pays off quickly. Offer acceptance rates improve, candidate experience improves, and your team spends less time running the wrong process for the wrong person.

Quick reference: all five mistakes at a glance

#	Mistake	Root cause	The fix
1	Vague, overloaded job descriptions	Wishlist mentality	Focus on outcomes, not credentials
2	Slow, multi-stage hiring process	No internal SLA	3 stages max, 3-day turnaround
3	Ignoring team fit and communication	Over-indexing on tech skills	Add structured behavioural interview
4	Losing candidates during onboarding	Hiring ends at signed offer	Day 1 checklist, buddy, check-ins
5	One-size-fits-all hiring process	No role-based tracks	Three separate hiring playbooks

The bottom line

None of these mistakes require a bigger hiring budget or a dedicated talent acquisition team to fix. They require honesty about where your process is falling short, and the discipline to address it systematically.

The companies that hire the best IT talent consistently aren’t necessarily the ones paying the most or with the most recognisable brand. They’re the ones that run a clean process: clear expectations, fast decisions, a genuine welcome when someone joins.

That’s achievable for almost any company — but it rarely happens by accident. It takes deliberate design.
