How it works

Practise. Keep your best. Share the interview.

1. Choose your experience

Try a free 10-minute preview first, or choose a separate 30-minute certification assessment. Pick your seniority; the questions move with it.

2. Read your feedback

The preview includes private practice feedback, recording and transcript. The full assessment explores more skills and unlocks certification and controlled sharing.

3. Send it instead of a resume

One link per hiring manager. They verify with a work email, watch the interview, read the sealed assessment — and you see who opened it.

Before your first attempt

Network Engineer mock interview — questions candidates ask.

How long is the Network Engineer mock interview?

You get one free 10-minute practice preview. The Certified Resume plan — $30 every 3 months — includes one 30-minute assessment and unlimited controlled sharing. Renews automatically every 3 months until you cancel. Got hired? Cancel in one click.

What level is the interview pitched at?

You choose before you start. This role is offered at Entry / Junior · Mid-level · Senior · Lead / Staff / Principal · Manager · Director / Head of; the questions and the bar move with the level you pick, so a director is not asked entry-level questions.

What do I get at the end?

The 10-minute preview provides brief private practice feedback, not a certificate. The separate certification assessment provides a recording, transcript, role-specific AI evaluation and a scoped SealHire badge in your shareable profile.

Can I share it with a recruiter or hiring manager?

Yes — your Certified Resume can be shared while your plan is active, with one link per application or a public Seal link. Every assessment stays on your account; the one you mark Primary is what your link shows. The recording and other protected sections open only to a hiring manager who verifies with a work email, you see who opened it, and you can revoke any link. Free previews stay private.

Is this a job opening at a company?

No. It is a realistic Network Engineer role brief — the kind of interview you would face for the role — not a vacancy at a specific employer. Practise here, then share your best attempt with the employers you apply to.
