High Level Design (HLD) in Dublin, FAQs

Yes. The High Level Design (HLD) course is delivered 100% live online, so learners across Dublin, Leinster join the same batches as everyone else. Sessions are scheduled to fall inside working-friendly hours in GMT / IST (Irish time) โ€” typically early morning or evening locally โ€” and every class is recorded for lifetime revision. Fully personalised 1-on-1 slots can be booked at any hour that suits you.

Batches are announced in GMT / IST (Irish time) as well as IST. Because our trainers are based in India, the natural overlap is early morning or late evening GMT / IST (Irish time), which works well alongside a full-time job. If none of the running batches fit, a 1-on-1 track is built entirely around your calendar.

Fees are quoted in EUR (โ‚ฌ) equivalent on request, and international learners can pay by card or bank transfer. WhatsApp +91 9180377502 for the current High Level Design (HLD) pricing, the next batch date in GMT / IST (Irish time), and the 1-on-1 option.

Every session is live and interactive โ€” live coding, screen sharing and real-time doubt-clearing with a working High Level Design (HLD) engineer, not a recorded playlist. Recordings are provided afterwards so you can revise or catch up if a session lands awkwardly in GMT / IST (Irish time).

You receive a course completion certificate you can add to LinkedIn and your CV. Like any training certificate, it supports your application rather than replacing employer screening โ€” in Dublin, Leinster what carries the interview is your project portfolio and how you perform in the technical rounds, which is what the live sessions are built to prepare you for.
