What is a L1 Technical Support Engineer pre-screening interview?
A L1 Technical Support Engineer pre-screening interview is a short first-round screening — typically 15–30 minutes — designed to verify that a candidate meets the baseline qualifications for the role before committing to a full interview panel. It covers professional background, specific past experience examples, and role-relevant knowledge or skill questions. The goal is to surface candidates worth a deeper investment and identify unqualified applicants early — saving hiring manager time at scale.
How to run a L1 Technical Support Engineer pre-screening interview
- 1Select 6–8 questions from the list below
Pick a mix of question types — at least one about background and track record, two behavioral questions asking for specific past examples, and one situational or motivation question. Avoid asking all 20 — focused calls produce better, more comparable answers across candidates.
- 2Block a consistent 20–30 minute time slot
Consistent duration keeps comparisons fair. Inform candidates of the time commitment in the invite so they come prepared, not rushed.
- 3Score on a 1–5 scale per question, immediately after the call
Define what strong, average, and weak answers look like before the first call. Score within five minutes of hanging up — memory degrades fast across multiple candidate conversations.
- 4Advance candidates above a pre-set minimum threshold
Set the pass score before your first call, not after reviewing results. This is the single most effective way to remove unconscious bias from the screening stage.
