-        I'm so grateful to know this amazing "Tech Interview Handbook"! It
-        really helped me to understand the entire recruitment process starting
-        from the very beginning stage until getting the offer (and negotiation).
-        Furthermore, I really love "Algorithms study cheatsheets" section since
-        it's really concise and helpful. Following the advice in this handbook
-        helps me to ace and get the offers from FAANG and other top tech
-        companies.
