How to Research Companies Before Applying (EU 2026 Playbook)

Glassdoor's 2025 EU Hiring Report shows that candidates who spend at least 30 minutes researching a company before applying receive first-round interviews at a 41% higher rate than peers who apply immediately after seeing a listing. Research is not just for impressing hiring managers - it is for filtering out bad-fit companies before you waste hours on applications.

This guide breaks down the exact research steps for EU companies in 2026: financials, culture, compensation, legal structure, and the subtle signals that predict a great (or terrible) employee experience.

Why does company research matter?

Three reasons:

1. Filtering. 20-30% of EU companies that look exciting externally have major red flags once you dig 30 minutes deep. Better to discover this before spending 4 hours on an application and 2 hours on an interview.
2. Tailoring. A cover letter referencing the company's recent product launch, fundraising round, or strategic pivot dramatically outperforms a generic one.
3. Negotiating leverage. Knowing the company's funding, margins, and market position makes salary negotiation sharper.

Where do you start researching a company?

Step 1: Official sources (15 minutes)

• Company website. Read the About page, the blog, and the careers page. Look for values statements, leadership bios, recent posts.
• LinkedIn company page. Check employee count, growth rate (Insights tab), recent hires and departures.
• Annual reports. If listed on a European exchange (Euronext, Deutsche Borse, London), read the latest annual report. If VC-backed, check Crunchbase and Sifted.
• Press releases. Last 3 months. What are they announcing? What are they NOT announcing?

Step 2: Employee voices (15 minutes)

• Glassdoor / Kununu (Germany). Read the most recent 20 reviews. Do not trust a single average score - read for patterns.
• LinkedIn employee feed. Search "[company name]" in LinkedIn posts. What are current employees saying publicly?
• Blind / Teamblind (tech). Anonymous reviews, often more honest than Glassdoor for tech companies.
• Reddit. Search "[company name] review" on r/cscareerquestionsEU, r/eu4, or country-specific subs.

Step 3: Financial health (10 minutes)

• For public companies: market cap, revenue growth, profit margin, recent earnings calls.
• For private / VC-backed: Crunchbase, Sifted, Dealroom, EU-Startups - last funding round date, amount, and investors.
• For SMEs: Kompass, Chamber of Commerce filings, national business registers (Handelsregister for Germany).

Step 4: Culture signals (10 minutes)

• Leadership team on LinkedIn. Tenure of the CEO, CTO, and head of your function. High turnover in senior leadership is a red flag.
• Employee tenure. Browse 10-15 random employees' LinkedIn profiles. If average tenure is under 2 years, watch out.
• Glassdoor management rating. The aggregate score matters less than the trend (up/down over 6-12 months).

Step 5: Industry context (10 minutes)

• Direct competitors. Who does the company compete with? How do they compare on salary, culture, and growth?
• Industry trajectory. Is the sector growing or shrinking? Regulatory headwinds?

What red flags should trigger a pass?

Financial red flags

• Recent layoffs (check layoffs.fyi)
• No funding round in 24+ months for a Series A+ startup
• Declining revenue for 3+ consecutive quarters
• Frequent CFO turnover

Culture red flags

• 30%+ of Glassdoor reviews mention "overwork," "long hours," or "toxic"
• Multiple senior departures in 3-6 months (sign of internal conflict)
• Social media absence or dead blog (signals weak marketing investment)
• Vague or evasive answers on LinkedIn to direct questions

Legal / compliance red flags

• History of GDPR fines (check CNIL, BfDI, or other national DPA databases)
• Labour disputes or strikes in recent news
• Tax disputes or corporate governance scandals
• Sanctions or export-control concerns (for EU companies doing business in restricted markets)

What green flags indicate a strong company?

• Consistent 4.0+ Glassdoor score over 12+ months
• Leadership tenure 3+ years in key roles
• Growing headcount but not explosively (25-50% per year signals healthy growth; 200%+ often signals chaos)
• Recent positive press coverage from credible outlets (Sifted, TechCrunch, EU-Startups)
• Clear and specific values statement with observable examples
• Transparent salary bands published externally (rare but very positive)
• Clear remote / hybrid policy written publicly
• Active engineering blog or open-source contributions (for tech companies)

What to research specifically for EU companies

Legal entity structure

• GmbH (Germany), BV (Netherlands), SAS (France), SL (Spain), S.r.l. (Italy): standard private companies
• AG / SA / SE: listed or larger companies, often more stable
• Startups in public / VC-backed private markets: check burn rate signals

Compliance

• Data protection. Has the company had any GDPR fines? (Databases: enforcementtracker.com, CNIL decisions, BfDI rulings.)
• Employment law. Check if the company has any reported works council (Betriebsrat, Ondernemingsraad) disputes.
• Financial reporting. Listed EU companies must file annual reports. Private companies in Germany, France, and others must file accounts.

Labour and works councils

• Betriebsrat (Germany). Companies with 5+ employees can have one. Works councils affect hiring, firing, and workplace rules.
• Comite social et economique (France). Similar role.
• Ondernemingsraad (Netherlands). Same.

Research whether the company has these and how well they function.

Pensions and benefits

• Germany: Check if the company offers bAV (betriebliche Altersvorsorge)
• Netherlands: Industry-wide pension funds (PFZW, ABP) often apply
• France: Check mutuelle (health) and retraite (pension) provisions
• Scandinavia: Usually extensive; confirm specifics

Sick leave and parental leave

• Germany: 6 weeks full pay, then 70% via health insurance. Parental leave up to 3 years.
• Netherlands: Up to 2 years at 70% pay. 16 weeks maternity at 100%.
• France: 16 weeks maternity, 25 days paternity. Check company top-ups.
• Nordics: Most generous - up to 480 days parental leave shared between parents.

Research what the company does on top of legal minimums.

How do you research culture without joining first?

Talk to current and former employees

• Message 3-5 current employees on LinkedIn asking for a 15-minute informational chat
• Message 2-3 recent departures and ask frankly why they left (most will be honest if you ask diplomatically)

Analyse public content

• Read the company's latest 10 LinkedIn posts
• Read the engineering blog or newsletter if it exists
• Watch their CEO/founder's public talks

Attend events

• Many EU companies attend industry events (Berlin Buzzwords, Dublin Tech Summit, Slush Helsinki)
• If you can attend, observe how employees interact, what they emphasise, who is engaged

Research depth by role seniority

• Junior (EUR 30-50k): 20-30 minutes of research is enough
• Mid (EUR 50-80k): 45-60 minutes
• Senior (EUR 80k+): 90+ minutes including 1-2 informational interviews
• Leadership (EUR 130k+): 3+ hours, multiple informational interviews, sometimes a paid consultant for in-depth analysis

Common mistakes

• Relying only on Glassdoor aggregate score. Read the reviews themselves, especially recent ones.
• Skipping financials. A great culture at a dying company is a 12-month job.
• Ignoring works councils and pension funds. These are huge quality-of-life factors in the EU.
• Not reading the engineering blog. For tech companies, the blog reveals actual engineering culture, not marketing claims.
• Applying without knowing the CEO's name. Basic competency.

How to use research in your application

• Cover letter: Reference one specific recent event (fundraise, launch, pivot). Show you did homework.
• Interview prep: Prepare 3-5 company-specific questions that show you understand the business.
• Salary negotiation: Know the comp bands, last funding round, and realistic ranges before the offer conversation.

A 60-minute company research template

For a mid-senior application, run this checklist:

• 0-10 min: Company website. About, blog, careers, leadership bios. Note product positioning.
• 10-20 min: LinkedIn company page, employee growth trend, recent hires/departures.
• 20-30 min: Read 15-20 most recent Glassdoor / Kununu reviews. Look for patterns, not averages.
• 30-40 min: Financial health. Annual report if public; Crunchbase / Sifted / Dealroom if private.
• 40-50 min: News. Last 90 days. Search "[company name]" on Google News and Sifted. Flag any red-flag stories.
• 50-60 min: Identify 2-3 employees to reach out to for informational interviews. Note specific shared context for each.

Save notes in a structured doc. Reuse across interviews.

Questions to prepare for the interviewer

Strong candidates bring 5-7 specific questions. Weak candidates ask "what's the culture like?" Examples tailored to your research:

• "Your last Series B deck mentioned expanding into France. How is that going, and how will this role support that?"
• "Your CTO blogged in October about migrating from monolith to microservices. Where is that effort today?"
• "Glassdoor reviews mention on-call burden. How is the team addressing it, and what does on-call look like in the first 90 days?"
• "The 2023 annual report noted declining margins in the B2C segment. How is the team thinking about that market?"
• "I noticed three senior departures in the past 6 months. Can you share context on what is driving that?"

Questions grounded in research signal seriousness. Generic questions signal a checkbox mentality.

Checking founder and executive backgrounds

For startups especially, the founders and execs often determine company trajectory. Run a 10-minute check:

• CEO LinkedIn history. How many years at each role? Any flameout companies?
• Prior companies. Were they acquired, IPO'd, or quietly shut down?
• Public talks, podcasts, interviews. Watch one or two. How do they talk about employees?
• Company-culture fit signals. Is the CEO's public persona aligned with your values?

A CEO who has shut down 3 companies in 5 years is a data point. Not necessarily negative, but worth noting.

When should you walk away before applying?

Sometimes 30 minutes of research is enough to cross the company off your list. Walk-away triggers:

• Glassdoor score under 3.0 with recent "toxic" and "burnout" reviews.
• Active wage disputes or lawsuits.
• Layoffs in the past 3 months with no public recovery plan.
• Leadership turnover of 50%+ in senior ranks over 6 months.
• No funding in 24+ months and no profitability story.
• Multiple GDPR fines or regulatory actions.

Two or more of these means do not spend 4 hours on the application. Move on.
