The interface is easy enough for anyone who has basic computer skills (and some people don't even need those) but also allows advanced users as well! I think it's great how they offer both free versions of their products AND paid ones which are very helpful if one doesn’t want or cannot afford all features at once - especially when there may be different levels within each product too!! It helps me find potential employees quickly by using many aspects from intelligence testing through technical questions etc., plus i'm able to give them feedback easily via text messages/emails without having someone physically present during interviews-which saves time & money overall.
