When responding to an interview request, try your best to accommodate the employer’s suggested day and time. If the appointment clashes with your schedule, offer an alternative option that allows you to arrive at the interview with ample time to spare.
When planning travel time, account for unforeseen issues like traffic jams, the need to clear security lines or difficulties in locating interview venues.
Ensure you have your route mapped out the day before the interview. Some offices are located in far away in industrial parks where transportation is limited. Plan your travel accordingly.
