If they have advertised for employees and they don't respond to an application, then they aren't a decent outfit. It also speaks volumes as to their attitude to employees. IMHO.
That MIGHT be true, but...my email address is used quite extensively for our flight planning etc. Works mighty fine but for a few recipients, that never get my emails or only selectively. For example, very often when I dropped a handling/slot request at LCY Jetcentres email address, its not found at all after an confirmation call or sometimes in the spam folder. Has gotten better in recent times for no (to me) apparent reason. I used the same computer, mail program and address for many years. Wetehr they changed anything or my complaining did some good - I donīt know. So, email is not 100% assured delivery, even when 99,9% of your emails go through, some donīt.
