A pre-interview NDA protects the employer's confidential information shared during the hiring process. Most of the time, signing is fine. The risk is when the NDA is overbroad — covering more than just what's discussed in the interview, lasting longer than necessary, or missing standard carve-outs that protect you.
Why companies require NDAs before interviews
Companies ask candidates to sign NDAs before interviews for legitimate reasons: they may share proprietary product details, unpublished financial information, unannounced business strategies, or technical architecture during the interview process. They want to ensure you can't share that information with competitors or the public if you don't get the job. This is reasonable for most roles, especially senior positions or those involving sensitive technology.
What to check in an interview NDA
Four things matter most in an interview NDA. First, scope — what counts as 'confidential information'? A definition limited to 'information marked confidential' or 'information disclosed during the interview process' is reasonable. A definition covering 'all information of any kind' is overbroad. Second, duration — 1–2 years is standard; indefinite duration is unusual. Third, carve-outs — the NDA should exclude information you already knew, information in the public domain, and information you received from other sources independently. Fourth, purpose limitation — the NDA should only restrict use of confidential information for competitive purposes, not restrict you from working in your field.
Does an interview NDA restrict your future employment?
A pure confidentiality NDA should not restrict your employment. The restriction should be on disclosing specific confidential information, not on where you work next. Watch for NDAs that bundle confidentiality restrictions with non-compete or non-solicitation language — these are sometimes slipped into interview NDAs and are separate from the reasonable confidentiality ask. If an interview NDA contains non-compete language, that's worth flagging.
Is it okay to ask for changes to an interview NDA?
Yes, though the practical reality depends on the company. At a large company with standardized legal processes, they may not be able to customize the NDA for each candidate. At a startup or smaller company, asking for a modification to an overbroad clause is often accepted. The most common reasonable ask is tightening the definition of confidential information or adding standard carve-outs if they're missing.
What happens if you sign an overbroad interview NDA
If you sign and don't get the job, the NDA continues to apply to whatever confidential information was shared. In practice, most companies don't pursue former candidates for NDA violations — the information shared in an interview is rarely sensitive enough to justify litigation, and the cost of enforcement is high. The real risk is if you joined a competitor shortly after and the company believed you used their confidential information. This is the scenario NDAs are designed to address.
