Customer Support Specialist resume do's and don'ts
- Do: Lead every bullet with an outcome and a number: “Reduced average first response time from 6 hours to 38 minutes.” Don't: List duties without results: “Responsible for answering customer emails and chats.”
- Do: Name your exact stack — Zendesk, Intercom, Salesforce Service Cloud. ATS keyword matching is literal. Don't: Write “various ticketing and CRM tools” and expect the parser to guess what you used.
- Do: Show both volume and quality: tickets per day plus CSAT, first-contact resolution, and SLA compliance. Don't: Claim you handled “high ticket volume” with no number or quality metric attached.
- Do: Demonstrate escalation and cross-team work: bug reports to engineering, voice-of-customer reports to product. Don't: Frame the role as only closing tickets — that reads as entry-level scope, not specialist scope.
- Do: Spell out the acronym and the phrase once: “customer satisfaction (CSAT)” and “service level agreement (SLA).” Don't: Keyword-stuff — repeating “customer service” twenty times reads as spam to reviewers and scoring engines.
