Just be VERY careful!
I went for an interview a good few years back - younger and more niave than I am now. The interview was held at some plush offices in Reading. I was shown in by this tastey secretary to be interviewed by a couple of guys in flash suits and even flasher laptops.
anyways the interview went well and I thought id hit the jackpot when I was offerd the position! I accepted of course and handed in my notice with my present employer....
...BAD MOVE.... VERY BAD MOVE!
..>Turns out the head guy was a total bullshitter. He was a one man band (the other guy turns out to have been his auld fella out on a jolly, if you can believe that!) the offices where not his - he had rented them for the day (with the techno IT kit too!) and infact had no offices himself at all, no kit and not even a registered company. I only found all this out when I turned up to meet him on my first day.....
I got home from work that evening, wife asks 'So! How was your first day in your new job then?'. 'Well, errrr...., not great if truth be told' as the realisation that I had just made a HUGE mistake dawned.
I turned up the following day, same crap as before so at lunch I said to this guy I was just nipping the shop for some lunch. Never went back. That job lasted a total 1.5 days - good job I hadnt signed anything at that stage.
Beware - Things are NOT always what they seem!
