Interview through recruiter.
Interview through HR.
Interview then through someone technical if you're lucky.
Generally the experience was a little unprofessional as the role was not clearly defined from the impression past the recruiter. It seemed that overall there was a misunderstanding of what an IT engineer is in this position - and they did not know what they were looking for. ALARM BELLS?! Yes.
Be careful - easy interviews, but you may just end up out of your league as they refuse to mention all their roles have account management, pre-sales and sales works involved in them. You have been warned.
