Regarding these interviews - Well it was all very friendly!!!
Tech interview: Asked about questions I didn't get quite right in the selection tests basically. Definitely learn about the tracks used over the Atlantic (different wind speeds etc, head and tail winds and their uses). Also VOR and DME (and lots of other initials) are very useful to know.
Don't forget how to calculate distance (use the DST triangle - think back to your school days!!!!)
He/she will ask you about visits to a tower or centre so make sure you have been to at least one.
Don't forget to mention the 'characterisitcs' of a controller: calm, organised, good-communicator, etc.
Personell interview: what can I say really? Give some very good reasons why you want the job, think of situations you have been in that show: patience, calmness, common sense, time management, how you cope under pressure, and if you've ever bent the rules.
Just talk lots about what you've done with your life so far and why you have chosen ATC as a career.
Computer test: lots of fun! READ the instructions and use the practice time very wisely, you can take as long as you like for practice. It's all about reaction times and recognition. The nasty ones are the number matching questions, but just PRACTICE!! Make sure you are completely sure before you press that 'continue' button.
Good luck to anyone still to take an interview. Hopefully see you in April.
