Acumen Research Laboratories interview questions

The CEO initiated the connection via LinkedIn and wanted to do a have an exploratory chat. After agreeing to her proposed timing, I called her on her mobile but was in vain. Message and call were not attended to. An hour later, she finally responded saying she's available to do the call without even apologizing or explaining why she did not show up earlier. It's a poor reflection of her as a leader for the company. She doesn't even have the basic respect for other's time. It was definitely an unpleasant experience.
