Sales interviews are one of the few interview types where you're being evaluated on the interview itself, not just your answers — how you handle the conversation is treated as a live sample of how you'd handle a prospect call.
Vague numbers are the biggest tell. "I was a top performer" without a specific quota percentage, deal size, or ranking reads as unverifiable. Interviewers in sales roles expect you to speak in the same concrete, metric-driven language you'd use to run a deal — because that's exactly what they're hiring for.
Bring three specific numbers to the interview: your best quarter (with the actual percentage), a deal you lost and what you learned, and a metric you personally improved (response rate, average deal cycle, upsell rate). Practice your discovery-call questions out loud — sales interviews move fast, and rehearsed structure beats improvising.
KrackerAI builds a report from your resume and the specific sales job description — role-play-style questions matched to that company's product and sales motion, plus company research so your discovery questions sound informed rather than generic.
