When you’re looking for a job, a good rule of thumb is to answer your phone as often as you can. You never know when a recruiter might be calling to set up an in-person meeting, or conduct a phone interview.
If you aren’t sure, have a friend listen to it and give you pointers. It’s always disorienting listening to your own voice, so you might not be able to catch if you sound weird because you’re hearing your voice or because you are actually speaking in a strange manner, but someone who knows you well will be able to clear it right up.

It’s more important that your callers feel like they can ask you for help on a subject they don’t know too well. A really easy way of simplifying your greetings is by using smaller words. Imagine yourself explaining what you want to a three-year-old. Your customers aren’t stupid, but they’re not going to always be familiar with typical business jargon. Make sure you’re adjusting your greetings to accommodate for the lack of familiarity, unnecessary details, and technical information.
You can also make use of a 3rd party option and use a crowdsourcing professional voicemail greeting provider such as Fiverr to record your voicemail greeting. Fiverr is flexible, fast and affordable and at just $5, you have the option of choosing between hundreds of professional voice-over actors who can record your script. You can also find professionals who can record voicemail greetings in various languages, accents, etc. at very affordable prices and deliver the recording within 3 working days or less.
