What I like best about this service is its simplicity, as it requires no programming or advanced knowledge other than that of English language for successful results; plus, you can reach them even if your phone cannot detect their location! One thing I don't know much about, but my colleague said he has been receiving calls without being informed by email beforehand (such an inconvenience); so at times one feels left out with zero prior information concerning any important meetings/dates in question which are set via appointment scheduler system within another department - just when all staff members have signed up using shared access key code generated from HR admin page itself! This should be made more user friendly especially through automated updates using cloud services such Google calendar etc., instead requiring manual input every time there's need to change schedule dates & appointments.
The speed of getting through applications is great! Sometimes there are too many applicants for one position so it can take time but that's only because they're all pretty good, not just bad ones like some other companies I have used before. It makes finding qualified people much easier than having to go from page to page looking at hundreds if you don't get lucky right away. They also post jobs quickly which helps with my ability to find new positions as well.
