Imagine yourself walking out the door after one of your greatest interviews ever; with that big smile on your face and being 100% confident you'll get the job. That's what I want to achieve by writing this book, which is full of tips, problems, and answers that will get you hired.
Technical interviews are very different compared to normal ones and the golden rule is always to spend enough time and effort on preparation. This doesn't mean you don't need people skills. You need them for sure and I'll tell you during the course why. In the end, my goal is to make you enjoy the process of walking to an interview.
However, if you feel like an interview has not gone well, just consider it a learning experience.
The book is split into 3 major parts: the first one for beginners, the second one for intermediate developers and the third one for seniors, so you can skip to the section you’re interested in. However, I recommend you go through all of them because a hard question for me can be an easy one for you and vice-versa.
Each of the 3 major sections can contain lectures from C#, SQL, Javascript, HTML, CSS or GIT areas, so I’m covering everything a full stack developer can be asked during an interview.
By the way, I’m happy to receive feedback from you. If you think a question is not presented or it’s not presented very well, just let me know and we’ll improve it together. I’ll make sure you are mentioned.
