Rotate it out for now. If you take a break from this particular type of question for a few days, can you still solve it within the time limit when you try it again next week?

Trying to get in at one of the top tech companies in the world? This technical interview prep course from Big Machine includes 5 hours of video for you spread over 18 lessons that will teach you the strategies and techniques your peers use to pass tough tech interviews. It may not seem important now, but I highly recommend that you start using just one language while you practice answering technical questions. This way you’ll not only get better and more experienced in that language, but you’ll also not run into any hidden issues by accident on the day of your technical interview. Which language should you use for your technical interview? Many people argue that LeetCode premium is not worth it, though writers like Yangshun Tay beg to differ. What interests me about LeetCode is not their premium option, but that they make so much of their service available without it. There is no one-size-fits-all answer to this one! It depends on your learning style, which languages you’re training for, etc. Sure, the interviewer cares that you know the most important elements of how the language, tools and libraries work (or that you can learn them), but they won't ask specific questions about it, and if they do, its extremely rare.If you’ve applied to a bunch of jobs though, then it’s totally fine for you to reply, be positive, and then ask for some time to decide. Make sure to be super thankful for the opportunity and ask for a day or two, and then let the other companies that you’ve applied for know that you have an offer. This happens a lot in the tech industry so don’t feel bad about this. It’s simply showing that you’re in demand, and you can even use this as leverage to negotiate salary.

This code interview course of the University of California San Diego was put together with the support of Google’s recruiting and engineering teams, so you know you’re getting relevant advice. It takes about 21 hours to complete the videos, reading, and exercises, so it’s doable to prepare for a coding interview in one week with this technical interview preparation course. I have used interviewing.io, both as an interviewer and an interviewee. The experience was great. Aline Lerner, the CEO and co-founder of interviewing.io, and her team are passionate about revolutionizing the process for coding interviews and helping candidates improve their interview skills.An additional benefit of this, is that it means that these new hires can move around between departments if needed for a task or project. They specialize in one area but can work in others if needed for a sprint etc.

Achieve a balance between accuracy and efficiency. Use the right amount of functional and imperative code where appropriate. Functional programming is usually expensive in terms of space complexity because of non-mutation and the repeated allocation of new objects. On the other hand, imperative code is faster because you operate on existing objects. Don’t get too complex just yet. Often the simple solution is best, so ask yourself, what’s the brute force approach to solving this? Talk through your thought process. You don’t need to write any code just yet, simply think through a possible solution. Will this simple solution work? They’re usually less interested that you solved a problem correctly. They care more about your thought process and your approach to how you solved it. Thank them for taking the time to interview you and that meeting with them re-enforced how much you are looking forward to being part of their team I highly recommend using this same approach when solving practice questions on your own, so that you get into this step by step habit for solving, analyzing and working through your solutions.

Showing how interested you are in working there and getting started can never hurt your chances. Who do you think they want to hire? The quiet person who ends the call who they might forget, or the person wanting to start on Monday? Ending the coding interview Berger, Michele W. (2017).
