Purdicom Technical interview questions

I have to say this was with out a doubt one of the poorest interview experiences I've ever had. The interviewers thoroughly lacked any ability to engage properly or show any warmth or charisma. This left me feeling twitchy and nervous through out. Every question I answered seemed to be followed up by an awkward silence. I quickly came to the realisation that they had undertaken zero prior preparation beforehand. It became so off script that it essentially it boiled down to me to think of questions they 'ought to ask. Ridiculous. So summed up, the whole experience was a travesty. I arrived on time, up beat and positive. I travelled half way across the country to be there at entirely my own expense. And I left very frustrated and confused. Quite frankly, based on my experience I simply cannot recommend anyone consider committing to Purdicom. Stay away from this outfit.
