I worked as a Senior Engineer at Google for four years. Before that, I did my Master's Degree in Computer Science from the University of Waterloo, Canada. I have over eight years of experience in the North American tech industry.
While at Google, I have conducted about 70 interviews focusing on Data Structures and Algorithms, primarily for L3-L5 roles.
Unfortunately, there’s no set answer to that question as every situation is different. We recommend doing one or two sessions with a coach to get started. They’ll be able to give you an assessment of how many sessions you’ll need overall.
Yes, unused credits can be refunded within 30 days of getting purchased. After 30 days the credits cannot be refunded anymore, but you can still use them at any point in the future.
If you do get a refund it will be corrected for the discount you initially got. As an example, imagine you have purchased 10 credits, and paid 10 x $48 = $480. If you end up only using 5 credits, we will refund you the difference between what you have paid ($480), and what you would have paid had you purchased 5 credits (5 x $50 = $250). So in this specific example we would refund: $480 - $250 = $230.
Credits cost $50 to $40 per credit. The more you buy, the cheaper they get.
Coaches cost 2, 3, 4 or 5 credits per 1h coaching session.
