Timing is crucial for every interview and luckily it’s typically a part of the interview process you can control. According to multiple sources (cited below), Tuesday is the most productive day of the week. Research can even pinpoint it to 10.30am on Tuesday.
The line of thought here is that when your interviewer is at their best they are more receptive to your ideas and answers. Tip for interviews – if you feel that you’re perhaps not in the best mood, always try and switch to a positive mindset before an interview by either having a coffee break, go for a walk or play a quick game of ping pong (if you’re lucky enough to have one nearby). You always want to give candidate’s a fair chance.
But this is the general rule and not advice written in stone. When thinking about booking your interview, also consider:
- Avoid early mornings and end of day. You and your interviewer will (most likely) not be on top form.
- Avoid lunch interviews when possible. Hungry interviewers are bad interviewers.
- Try and find out when works best for your interviewer so you can catch them at their best.

“What’s the difference between a good joke and a bad joke timing”
In short, aim to interview at 10.30am on a Tuesday. Timing is key.
I interview a lot of people. And like any interviewer, there are times when I’m on top, productive and positive and times when I’m, well, just not. Why? Because I’m human.
