“Your sharding plan handles writes well. Talk me through what breaks first when one shard runs three times hotter than the rest.”

Who it's for

You made the shortlist. Now turn it into an offer.

Forward the interview email or paste the job description, and rehearse the exact loop that company runs, wherever you are in your career.

A confident young professional standing in a bright modern office lobby

Your first job

Graduate schemes and campus hiring loops: aptitude, technical, and HR rounds, rehearsed until they feel like old ground.

The next step up

Senior, staff, and leadership loops, with the system design and judgement questions that decide the level you're offered.

A change of direction

A new field, or back after a break. Practice telling your story until it sounds like a plan, not an apology.

How it works

Three steps from job post to game plan.

1

Forward the role

Send the shortlist email to your private Sherlock address, or paste the job description. We read the role and work out how this company really interviews.

2

Sit the real loop

Call up each round whenever you're ready. Speak or type, write real code, and answer follow-ups on what you actually said, not a fixed script.

3

Hear the truth, kindly

Honest scores, your answers rewritten stronger, a spoken debrief, and a packet for the night before. You'll know exactly what to practice next.

The product

It feels like the real thing, because it behaves like one.

The interviewer listens, reacts, and pushes where you're soft, the way a real panel would. Then it tells you, clearly and without the sugar-coating, what to sharpen.

Spoken debrief

“You're strong on data stores, and the cache-first redirect landed well. The thing holding you back is tradeoffs. In both rounds you gave a solid answer but skipped the options you ruled out. Say those out loud next time and this clears a senior loop.”

Every interview ends with a packet you keep: scores, gaps, and stronger answers. Take the full tour.

Trust

A lot is riding on this. We don't take that lightly.

You're putting your next job through Sherlock. Here is how we earn that trust.

Yours, and only yours

Your emails, transcripts and reports are visible only to you. We research the company and the role, never your interviewer.

Never shared, never sold

Nothing you say is shared with an employer, and your data is never sold. We handle it under India's DPDP Act; read how.

Honest, not harsh

Scores are set to the real bar for the level, with the reasoning shown, so you know why and not just a number.

Pay for the interview, not a subscription.

One price opens the whole case: the research, every round with a free retake, your scores, the spoken debrief, and the packet. Priced by the level of the role, which Sherlock reads from the job description.

Questions

Before you start.

How is this different from generic interview prep?

Sherlock builds the interview from your shortlist: the actual job description, how that company is reported to interview, and the bar for the level. Follow-ups respond to what you actually said.

Is my job search private?

Yes. Your emails, transcripts and reports are visible only to you. We research the company and the role from public sources, never your interviewer, and we never sell your data.

What if a round goes badly?

That is exactly what practice is for. Every round includes a free retake, the report rewrites your weakest answers, and the debrief tells you honestly whether you'd clear a real loop at that company.

What do I need to start?

A shortlist or recruiter email, or just a pasted job description, and ten quiet minutes. Voice works in Chrome; typing works everywhere.

Your next interview is coming.
Walk in ready.

Forward the role or paste the job description, and rehearse the real thing.
