The star rating is a representation of the overall rating, calculated as the mean of the client satisfaction rating, the average client interview rating, and internal interview scores.
The client satisfaction rating is the weighted average of client ratings, with weights based on reviewed work hours. When no client rating exists, the approval fraction (approved vs. reviewed work hours) determines it.
If the client satisfaction rating exceeds the overall rating, it becomes the star rating. In the absence of client ratings, if the average client interview rating is higher than the overall rating, it becomes the star rating. If no data is available, the star rating defaults to the internal interview score.

Sage
Gobi waited 15 minutes for him to speak on call but he had non stop technical issues on both zoom and hangouts, and didn't show his video or say a single word, he needs to work on his internet and work station setup. Then afterwards he did show up on a call and gave some sensible remarks regarding using sentiment analysis and deep learning for our use case. But his internet once again failed so we just sent him some 6 points to comment on in slack and let's see how he does on it.
