Essential coding interview questions, coding exercises and solutions!
Learn problem solving techniques that you'll be able to use in your next coding interview!

As you prepare for your next coding interview, have you ever thought:

• I wish someone will just walk me through some of these problems and explain what’s going on.

• I wish there was a set of the important coding interview problems so I can practice them easily.

• I wish there was easy to hard to level question that are asked most often in an interview.

Course content:

• I’m going to walk you through the essential coding interview questions and their answers.

• I’ve picked these particular questions because they are the types of questions that are asked most often in an software engineering interview on Google, Microsoft, Facebook, Amazon, Apple, Uber etc.

• I’m going to cover problems that use concepts such as arrays, strings, linked lists and trees.

• You’ll get a coding exercise in Python and Java for each problem, so you can get feedback on your solution right away.

• If you want to use any other language to follow this course, that’s fine too! Just remember to run your solution on your computer to make sure it works.

If you think you’re ready for this course, watch the preview videos and see if you can solve those problems!

No worries! Udemy have 100% money back guaranty, so nothing to lose!

See you inside!
