1. The course joining instructions were ambiguous, resulting in one employee travelling from Amsterdam to London to a location where he thought he was getting on-site instructor-led training, only to find that site was a remote video link into another UK location - which he could have done directly from Amsterdam without any travel!!! Another employee had travelled to the same site also under the same illusion. Not good enough. Clarity over whether the course location delivers an in-person or virtual experienced needs to be improved. 2. The multiple windows of the Hyper-V environment used for the labs was very difficult to navigate making it a source of irritation and frustration. This distracted from the learning experience. 3. Some of the labs just did not work for some attendees - the debugging was a useful extra-curricular experience but in some instances the "errors" could not be overcome - even by the instructor - the VM environment being used cited as the major contributor . (1), (2) and (3) are the reason why this course is marked down. 4. The instructor was excellent. 5. The course content and the concepts behind the labs were excellent. 6. having been through to the end of this review once, I find it is geared to providing nice "happy" answers. A more objective setting of feedback questions would have been appreciated, hence why all this text is placed here - there's no other placeholder to feedback what one really thought or got out of the investment in this course.
