Red Flags to Watch for When Hiring Customer Support Engineers
Most customer support engineer hires that fail were readable in the loop. Interviewers just did not calibrate around the signals that matter for the actual work.

Vague accounts of past tickets
Strong candidates can walk you through a specific ticket end-to-end: how they reproduced it, what they ruled out, what they escalated, and how the customer received the answer. Candidates who cannot give you that level of detail either did not do the work or did not reflect on it.
Discomfort saying "I don't know"
Support engineering is bounded by unknowns. Candidates who paper over gaps in the interview will do the same with customers. Look for the honest answer plus a plan for finding out.
Written communication that would not survive a customer inbox
Ask for a short written response to a redacted ticket. Look for clarity, correct scope, and a next step. This one exercise predicts on-the-job performance better than most interview questions.
Disinterest in the product
A candidate who has not opened your product before the interview and does not ask about it during the conversation is telling you something. Support engineers who love the product outperform on every metric.
