I was taken up by Pamela’s Big Interview 5 part free email series, and then before my interview with Google, I thought I should pay the fee, it was $120 for a month subscription. I found the 5 lectures to be fairly sufficient over the content in the app. I am not good at formulating answers, but the model replies in the app wasn’t so useful for my field as an architect and I went online and found another free website instead to formulate my answers. The fee I felt was very high and expected more. I only used it once and didn’t seem to require to use it again after the first round Review collected by and hosted on G2.com.
