One debugging question online interview and one programming phone interview. Cracking The Coding Interview is very useful and highly recommended for any interview process and plan ahead for any upcoming opportunity. Even with less preparation, just be enough confident for tackling any questions and start the modular approach, like what you need to do and then to do that thing, what different- different small tasks you need to fulfill and how this small tasks combinedly give you your desired result. It is kind of divide and conquer approach but very useful for thinking for any problem.
