Resource Development Associates Research Associate interview questions

Was quickly contacted for an interview after applying and then interviewed in person at their office. Very quickly after that I was contacted for a follow up online assessment. But after that multi-hour assessment, communication went nearly radio-silent and resulted in an off-putting end to the process some months later. I found it off-putting to ask for such a time commitment from the get-go with multi-hour timed assessments, just to go radio silent for months afterwards.
