Make it in Germany · Blue Card

German baseline; Tarifverträge and contracts can differ. Information only, not legal advice.

Requirements

Evidence anchors are the exact phrases from the pasted JD. Match is a rule-based read of the candidate text, not a recruiter decision.

Jargon decoder

Fast-paced

Workload

“fast-paced”

Understaffed and permanently behind; priorities change weekly.

Why it matters: Teams that plan well do not advertise chaos as a benefit.

Ask: What does a normal week look like? How often do priorities change?

EU Blue Card

Gate

“Blue Card”

A work-and-residence permit with salary and qualification thresholds.

Why it matters: The employer usually has to drive the application.

Ask: Does the employer sponsor a Blue Card, and at what salary threshold?

Degree required

Gate

“Master’s degree”

A hard filter on paper; "or equivalent experience" is the escape hatch.

Why it matters: ATS screens on degree fields before a human sees the resume.

Ask: Is the degree requirement strict, or is equivalent experience accepted?

Probezeit

Stability

“Probezeit”

Probation, often up to 6 months; notice can be shorter.

Why it matters: It is the easiest period for either side to exit; check the notice clause.

Ask: How long is the Probezeit, and what notice applies during it?

Tarifvertrag

Pay

“Tarifvertrag”

Pay and conditions may be set by a collective agreement.

Why it matters: The offer may be non-negotiable outside the band.

Ask: Is this role covered by a Tarifvertrag, and which group?

Hybrid

Management

“Hybrid”

Office days are mandatory in practice; the "flexible" part is the commute.

Why it matters: Hybrid policies vary wildly; the JD rarely states the real cadence.

Ask: How many days a week in office, and is it enforced?

Nice to have

Gate

“Nice to have”

Not required on paper, but the bar moves once there are enough applicants.

Why it matters: Nice-to-haves become tie-breakers, then filters.

Ask: How do you weigh nice-to-haves against core requirements?

13. Monatsgehalt

Pay

“Monatsgehalt”

A 13th salary is common but not statutory; check pro-rating.

Why it matters: It may be deferred salary rather than a bonus.

Ask: Is the 13. Monatsgehalt pro-rated, and when is it paid?

No reporting line

Stability

No reporting line or team size. It may be a new role, or one they would rather not describe.

Why it matters: A normal req names the manager and the team; the absence is information.

Ask: Who does this role report to? How big is the team?

New or backfill?

Stability

Not stated. Default to inheriting history.

Why it matters: A backfill begs the question of why the last person left; a new role begs for budget proof.

Ask: Is this a new role or a backfill? Why did the last person leave?
