Phone calls were acceptable.

The qualification of the interviewers was generally low. Some were convinced of false facts, although this may also have been due to misunderstandings, as some of the interviewers were not sufficiently proficient in the English language.

After arrival (!), the parameters, especially the nature of the activity (which was one of the most important parameters), substantially deviated from the description.

The no less trivial final round conversation ended with a smile and the question (phrased more indirectly than here) whether they had even read the job advertisement and the CV, which of course ended our communication (fortunately).

Not to be taken seriously.
