The gap

You can solve it.
Can you explain it?

Grinding in silence trains a different skill than the one you're judged on. Interviews are solved out loud — with someone listening, pushing back, and keeping time.

"Sounds good — walk me through it."

How to improve
Explanation — you couldn't articulate the O(n log n) cost of the sort on line 2. Say the complexity out loud as you write it.

Frequently asked questions

What actually happens in a session?

You open a LeetCode problem and hit start. A voice interviewer greets you, listens as you think aloud, pushes back with follow-ups, and watches your code as you type. When you finish — or the 30 minutes are up — you get a graded postgame report.

How is this different from just grinding problems?

Solving on your own is a different skill than solving out loud under pressure. Lade makes you explain, defend, and adjust in real time — the part of interviews that actually trips people up.

Do I need a card for the free plan?

No. Free is 3 full-length interviews a month with reports included — no card, no trial that flips into a charge.

What does Pro add?

$20 a month for 60 interviews — enough to run one or two full loops every day until the onsite. Same 30-minute sessions, with your graded history tracked on the dashboard.

Does it work on any LeetCode problem?

Yes. Open any problem page and start — no setup beyond installing the extension and signing in.

Is my audio private?

Yes. Audio is never stored, and all API keys stay server-side — never exposed to the extension.
