We would like to thank you for your valuable feedback and apologise for any inconvenience caused. Moving forward, we will pre-inform our candidates who are coming for our interview on the estimate time duration needed. The intention is for the convenience of our candidates to complete the interview within the same day, so that our candidates need not to come down to our office another time. Nevertheless, if our candidates could not complete the interview within the same day, we will be happy to schedule the second interview at their convenience.
