AlphaSights Entry-Level Analyst interview questions

I apply this job through the official websites. I received an online interview assessment about 1 weeks later which acquire me finish in 7 days. The questions in the interview are very basic and tend to know more about yourself. However, there is only 5 seconds to prepare for each questions and 30 seconds to answer.

I went through the online application process in mid December and was invited to the Hangouts portion of the interview (round 3? Or 2). When I went to sign up for an interview slot the earliest available slot was in the third week of February - a ridiculous amount of time between the two steps obviously. However I waited until February. When I tried to enter the Hangouts session on that day, I found that the session had been closed (made at one point and then deleted). I informed alphasights recruiting through their normal email address and also emailed two recruiters as well as interviewer. Nobody replied back. I didn't get an explanation, I didn't get a reschedule, nothing. Of course I should have checked up on the status of my application in between December and February - that's parts on me. But why couldn't Alphasights be professional and communicate with me?
