Java Engineer Hiring Process

Companies are giving extra effort to optimize the hiring process to find the perfect fit. Working with different companies, we witnessed the best and the worst practices when it comes to the selection process. Typically, the steps would be:


Prescreening is a video or phone call to collect the necessary information about the candidates background. A recruiter may ask you about education, previous experience, motivation to change job, and salary expectations. This step is also essential to candidates. By asking the right questions, you can decide if this opportunity is right for you. It will save you time if you learn something about the company or the project thats not on your plan.

On-site interview

Once you passed the prescreening, the company wants to learn more about your technical and soft skills. The most common practice is to combine technical and HR interviews into one day, saving both your and the companys time. If this is the case, prepare for both sides of the coin. Having a strong technical background is essential, but companies want to make sure that you can fit with the rest of the team well. Communication is a vital part of any software engineering team. You should pay attention to demonstrate your willingness to listen and provide feedback accurately during the whole process. Just as on any job interview, you will go through a few phases.

    What To Pay Attention To When Solving An Algorithm Question

    Front End Developer Interview Questions: 5 Big Things to ...

    A. Dont rush to solve, its ok to ask for a few minutes to think.

    B. When you do start solving, it is highly recommended that you talk about what youre doing, even if youre not sure about your thoughts. The examiner usually looks to understand your process of thinking. It is not always necessary to reach a perfect and working solution. If youre not comfortable talking aloud, or just not used to it, practice at home by solving some example questions.

    C. If you can, you should first write your plan of action in words or pseudo-code. This will show the interviewer that you do not rush to solve things and that you can plan.

    D. If you get stuck at the beginning, dont panic! Start with the simple things. Think about input and output. Solve edge cases.

    E. Pay attention to the code effectiveness of your solution. If you understand that the complexity is not really good, say it out loud, and try together with the examiner to reach a better solution.

    F. Its totally fine to ask questions. A good examiner will try to help you reach a solution.

    G. Youre usually expected to solve these type of questions on a whiteboard/piece of paper. Since its not how we usually write code, you may find its harder to think like this. This is again something that worth practicing beforehand!

    Explain What Are The Difference Between A Get And Post Request

    Both a GET and POST method are used to transfer data from client to server in the HTTP protocol.

    Describe A Recent Technical Challenge How Did You Solve It

    This question is your opportunity to show the employer that you have tackled past problems professionally and elegantly. It is important to think about these examples before the interview so they are ready to be shared when you are asked this question. Using your portfolio or website to show the interviewer the result of this challenge will make this a more valuable answer. An example answer to this question could be:

    “I installed a cached plug-in to lower latency on a website running a CMS. It worked but not as well as I had hoped for as it runs on Apache. To make it work better, I used the mod_rewrite module to define the rewrite condition so that I could run the caching plug-in through the .htaccess file. In doing so, I was able to bypass PHP and the Expiry directive and get the full speed of the plug-in.”

    Async Programming And Javascript Specifics

    Interview with a Front-End Developer

    Prep 5 hours

    Asynchronous programming is at the heart of JavaScript and code execution in the browser so a lot of companies now test for understanding of this fundamental concept. Many companies use an async problem in place of an extra algorithm based problem for frontend candidates as well. While good performance here can help your candidacy, a bad one will impact leveling potential. Most hiring managers think of async programming as something that can be learned, although it would take a strong algorithm performance to offset a weak interview here.
