I have to do "job interviews" on a more regular basis than most people.

My last one didn't go so well. Client was a bitch. I used to be really nervous before consultations but not so much anymore.

You just have to be confident and friendly. People respond well to positive energy. Don't be afraid to laugh and show personality at your interview. People are always under the assumption that you have to be serious when interviewing, but a nice personable attitude can get your really far.

I have another consultation with a client coming up soon. The lady sounded sweet over emails, so hopefully it goes well and I book the job.
