System Design track

“
Mock design interviews with engineers made the difference. After a dozen sessions I could explain trade-offs, sketch clean architectures, and defend my choices instead of guessing at answers.

“
Learning evals changed everything. I stopped tweaking models on instinct, built proper test sets, and started measuring each change. Our team now trusts the numbers before anything ships.

Q&A
  • AN

    Ananya

    Why rerank at all? Can't we just take the top 5 from the retriever?

  • SE

    Senior AI EngineerTUTOR

    Retrieval is tuned for recall. The reranker reads each doc against the question, so your top 5 are actually relevant.

  • RK

    Rahul

    Does reranking 20 docs add much latency?

  • Meera raised a hand
Ask a doubt…

  • College-friendly schedule

    Live classes every weekday evening after 6 PM so you never miss college or exams.

  • 1–2 hours of live code

    Hands-on coding sessions with doubts resolved live on the spot.

  • Small interactive batches

    Limited cohort seats so every student receives direct mentor attention.

  • 6 months full recordings

    Rewatch any cohort session anytime to revise concepts and prepare for interviews.

What's the difference between reranking and hybrid search?

Hybrid search changes what you retrieve by combining keyword and vector matches. Reranking changes the order afterwards, scoring each result against the question so the best ones reach the prompt.

FAQ

Questions,Answered

Can't find what you're looking for? Talk to our team and we'll help you choose the right track.

How do the live classes work?

Classes run Monday to Friday in the evening, after 6 PM, for 1–2 hours. Working engineers teach your cohort live in our interactive classroom, solving doubts and writing real code alongside you.

What if I miss a live class due to college exams or travel?

Every single session is recorded in HD with timestamps. You can rewatch any recording for 6 months after your cohort ends, and get doubts answered anytime in the community.

Do I need prior coding or AI experience to join?

No prior AI experience is required for beginner tracks (AI Full-Stack, Data Science, and DevOps). We teach core programming and fundamentals step-by-step before introducing advanced tools.

Who are the mentors teaching the cohorts?

Working engineers and tech leads from top tech companies — not theoretical trainers. They teach real-world best practices: Git collaboration, code reviews, unit testing, and cloud deployments.

How do daily assignments and code reviews work?

After each live class, you build a hands-on project task. Mentors review your GitHub submissions daily and provide actionable feedback just like a tech lead on a real engineering team.

How does the 30% student discount work?

Simply upload your college or university ID card during enrollment. Once verified, you get a flat 30% discount on all live cohort tracks, which can also be combined with no-cost EMI plans.

Can I pay the course fee in monthly EMI?

Yes! Flexible monthly EMI plans are available across all tracks starting from ₹1,667/month. Select your preferred EMI tenure at checkout with our payment partner.

What career and placement support do I receive?

6 months of dedicated mentor doubt support, comprehensive resume and GitHub portfolio audits, mock interview guidance, and lifetime access to our alumni hiring network.

Can I message my tutor 1-on-1 for doubt clearing?

Yes. Direct 1-on-1 tutor chat support is completely free throughout your cohort and for 6 months after graduation.

Will I receive a verified certificate of completion?

Yes. Upon successfully completing the cohort assignments and capstone project, you will receive an industry-recognized, shareable Certificate of Completion for LinkedIn and your resume.
