Support vacancies screen on three things: volume you handled, quality you held, and languages you speak. For EU support roles the language block is half the match — CEFR levels are keywords, not decoration. Numbers like CSAT and response time do the rest.
Keywords that appear in Customer Support job descriptions
- Zendesk
- Intercom
- ticketing systems
- CSAT
- SLA
- first response time
- live chat
- troubleshooting
- knowledge base
- escalation management
- CRM
- customer retention
- B2B support
- multilingual support
- remote support
Use only the keywords that are true for your experience — screening software matches them, but humans read them.

Common Customer Support resume mistakes
- No volume or quality numbers: tickets per day, CSAT, SLA compliance — without them 'provided excellent support' is unverifiable.
- Hiding languages or writing 'fluent': EU support postings screen on CEFR levels (B2, C1) — state them exactly.
- Only duties, no improvements: screeners notice the person who reduced ticket volume, not just answered it.
Summary line patterns
- Support specialist, 3 years in SaaS: Zendesk, 90+% CSAT, English C1, Polish B2.
- B2B technical support: APIs, logs, escalations — the tickets other agents hand over.
Knockout requirements to check before applying
