You can usually join directly at the scheduled time, but it depends on how the interview invite was sent.

If the email you received contains a meeting link (for example a Teams or Zoom link), then that is the link you will use to join the interview on 13 March. In that case, you normally won’t receive another email. You just join using that same link at the scheduled time.

If the confirmation email does not include a meeting link, then you will most likely receive another email closer to the interview date with the meeting invitation and link.

To be safe, I would recommend checking the confirmation email again and also looking at your calendar in case the meeting invite was added there automatically.

If you still don’t see a meeting link, it’s perfectly fine to reply to the confirmation email and ask them to share the meeting link for the interview.

If this solves your issue, please mark the answer as accepted.
