My HormonologyKim, a Hormonology newsletter subscriber, asks: “I had my first interview for a job in my high-energy Week 2 and bowled over the recruiter with my enthusiasm, sharpness and humor. But, now the company has asked me back for a second interview and it’s my Week 3. I’m worried that this low-ebb week is going to make me look unenthusiastic and uninterested in the job. And that they’ll think I’m two different people! Ha! What do you suggest?”

My answer: It’s true that in Week 3 you can appear tired, less emotive and, well, even downright bored due to rising progesterone coupled with lower levels of estrogen and testosterone, which sap your energy and excitement. However, if you know ahead of time these hormones will have these effects, you can easily override them! That’s because you can simply remind yourself to smile and gesture more, add more volume to your voice and pump up other aspects of your body language and personality that show you’re enthusiastic. And if you need a little extra help in the energy department, go ahead and down a cup of whatever caffeinated beverage you usually enjoy. (Just be sure not to overdo it—too much caffeine can amp up nervousness during stressful situations, such as job interviews.) Hope this helps!
