International calls for a practice interview: tips

Scheduling a practice interview across countries can get confusing fast. A time that looks convenient on your calendar may be too early, too late, or even fall on the next day for the other person.

Use the World Clock to compare local times, then confirm the proposed date and time in both locations before sending an invitation. A few checks can prevent a missed call and make the practice feel fair to both people.

Plan the interview time

1. Open the World Clock and compare the local times and time-zone offsets for both cities.
2. Choose a date and a starting time in your own city. Write down the other person's local time as well, including the date if it changes.
3. Check that date on a calendar before you settle on it. Time-zone offsets can change during the year when places switch to or from daylight saving time.
4. Send a calendar invitation that names both cities, states the date in words, and gives the start and end time. Ask the other person to confirm that the invitation appears at the expected local time.

For example, if New York is on UTC-5 and London is on UTC+0, a 10:00 a.m. start in New York is 3:00 p.m. in London. That five-hour difference is not guaranteed on every date. The two cities change their clocks on different days, so check the actual interview date rather than relying on a remembered offset.

Choose a time both people can manage

Both local times are during the day

This is usually the easiest option. A late morning start in one city may land in the afternoon in another. Leave a little room around the call so neither person has to rush straight from work, school, or another meeting.

One person would have to call very early or late

Try shifting the interview by an hour or two, or offer a different day. If the time cannot be changed, agree on it directly instead of assuming the other person is comfortable with it. A practice interview should help both people, not leave one of them exhausted.

The other person's date is different

A time-zone conversion can put the call on the next calendar day, especially when the participants are far apart. State the date for each person in the message, for example, “Tuesday, May 12 in New York, Wednesday, May 13 in Tokyo.” This is clearer than writing only “Tuesday at 9.”

The time-zone offset seems unfamiliar

Some regions use half-hour or quarter-hour offsets, and not every location changes its clocks seasonally. Use the cities themselves, not a guess based on a nearby country or a familiar abbreviation. For a second check on a scheduled meeting, see how to check a meeting time in UTC.

How to avoid a time-zone mistake

1. Name the cities. Write “9:00 a.m. Los Angeles time” rather than just “9:00 a.m.” Short abbreviations such as CST can refer to more than one time zone, so they are easy to misread.
2. Spell out the date. Use the month name, such as “October 6,” rather than a numeric date like 10/6. Numeric formats vary between countries.
3. Include the expected duration. If the practice interview should take 45 minutes, list the end time too. The other person can check whether the full slot works in their local calendar.
4. Offer more than one option. Suggest two or three possible dates and times, each with your city named. This gives the other person a chance to choose a reasonable hour.
5. Check the invitation after sending it. Calendar apps normally display an event in each viewer's local time, but a wrong time-zone setting or an incorrectly entered event can still cause confusion. Ask your partner to confirm the displayed start time and date.
6. Recheck after changing the date. If you move the interview to another week or month, check the offset again. A new date may fall on the other side of a daylight saving change.

Why the same city pair can have different offsets

Local time is based on a location's time zone, which is described in relation to UTC, the common reference used to compare times around the world. The difference between two cities can change when one or both locations adjust their clocks for daylight saving time. The change dates are not always the same, and some places do not change clocks at all.

That means a conversion you used for a previous call might be wrong by an hour for a new date. It can also make a recurring calendar event confusing if the participants' local clock changes happen on different weekends. For a one-time interview, check the exact date. For a recurring practice session, confirm each meeting separately around seasonal clock changes.

Before the call, send one short confirmation with the date, the time in both cities, and the expected length. That gives both interview partners a final chance to catch a mismatch.
