I have used Calendly at work, everywhere I've been, for the last 3 or so years. It's a lifesaver. I've also used other peoples calendly links, or teams scheduler, or chilipiper or any number of calendar scheduling system. When you're talking about scheduling two or more people of moderately busy schedules a "booking tool" like this is totally worth its weight in gold in any number of situations.<p>When I work with outside sales teams, from vendors, they often want to include other people (sales engineers, whatever). My calendar often gets chopped up into a few hours here and there of free time as most. I can sit down and write out what my schedule is for the next week but I'm not going to include every moment of free time, probably one or two big blocks per day - at most - if that's even available. They may be unavailable, or it might be late for them (West/East coast). However that one 30mn section I neglected earlier one day might have worked perfectly. But they don't know that. I send them a calendly, then they can look over all my free time and pick exactly what they want.<p>As a hiring manager, it's also great. People have jobs and lives. Calendly lets me say "here, pick anything that works for you". It gives them the control to not only pick a time that is convenient, but a time that they are comfortable with. Sure, maybe they could meet at 10am but they'd have to stand in a stairwell to take a call. However at 7pm East, they can be at home - and I'm totally ok with a 4pm call, my calendar is free after all.<p>The entire goal is to make the process of calendaring as convenient as possible for everyone involve. No more emails threads back and forth and back and forth and back and forth trying to find the best times. Especially when half the time you write out your availability to someone, 5 minutes later another meeting will appear in one of those open slots and throw everything for a loop.<p>Maybe there are ways that people send out these links that other people find offensive. Communication is always hard. But the goal is to reduce friction and make life easier. I will <i>never</i> be upset by someone trying to make my life easier by saying "Here, pick whatever works best for you on my caelendly".
