    I applied online. The process took 4+ weeksinterviewed at Lab49.

    Interview Details

    I first received a phone screen from the recruiting manager. Then I got another call with a senior designer, mostly talking about my background and questions about Lab49. Then I got called for in person interview, with hours of challenging design exercise and some HR talks.

    Front-End Web Developer Interview

    Anonymous Interview Candidate in Bethesda, MD
    Application Details

    I applied through a recruiter. The process took a weekinterviewed at Lab49 in November 2014.

    Interview Details

    I was contacted via LinkedIn. The recruiter was positive and made me feel confident that I'd be able to work for them. He said they were looking for individuals with knowledge of HTML5, CSS, and JavaScript. The actual interview was a much different experience. I felt like I was taking a computer science exam from my undergraduate days, and all the focus was on JavaScript. I received no questions about HTML5 or CSS.

    My interview was spread out over two phone calls. The first phone call was with two engineers. One did all the talking while the other stayed on mute. They asked me questions about JavaScript scope management, new standards appearing in ECMAScript 6, how to force scopes using call and apply, JavaScript object inheritance, automated testing, and how to test asynchronous code. This interview did not go well for me. I thought I would be rejected after this. To my surprise the company scheduled a second phone interview.

    For my second interview the engineers immediately went into algorithms. I believe we spent over 10 minutes on the first question. The problem I was given had to do with ensuring a certain quantity of parentheses had matching pairs. The solution I provided worked for the requirements given. The engineer wasn't satisfied with the performance of the algorithm. Thus, he kept adding requirements. After the second modification to the requirements he came out and asked that I devise an algorithm with O(n) performance. When he realized I wasn't going to give the answer he expected he asked if I knew what a stack was to which I responded "yes." I had actually clarified towards the beginning that ideally we would write a recursive algorithm but I wouldn't know how to explain the code over the phone.

    From that point forward the second interview just got more uncomfortable. I felt a tone of condescension in the remaining questions. When I tried to inject humor into the conversation I got no laughs. The second engineer was also on mute and rarely spoke. The second interview was the nail in the coffin as I got a rejection letter several days later.

    My conclusion is that the company sets a high standard for the engineers they wish to hire which I totally understand. I just wish the recruiter would have made this clearer from the beginning so I wouldn't have gotten my hopes up.

    Interview Questions
    • If you were given a string with any combination of matching parentheses, write an algorithm that ensures no set of parentheses are left unmatched. No other characters except for parentheses will be in the string.   View Answer

    Senior Software Engineer Interview

    Anonymous Interview Candidate in New York, NY
    Anonymous Interview Candidate in New York, NY
    Application Details

    I applied online. The process took 2+ weeksinterviewed at Lab49 in April 2014.

    Interview Details

    Interview process was quite technical. It started out with the Lab49 recruiter herself asking a series of technical questions with 2 choices. Then came 2 phone interviews where the interviewers asked the usual multithreading concurrency framework, object oriented programming and spring questions. The 2nd phone interviewer asked me to design a class which would execute parallel tasks in a non-blocking fashion. The 3rd interview was on skype with a senior staff engineer from Lab49. This was more design oriented and the interviewer was not very patient with me and seemed to judge me from a pre-conceived bias. He barely asked me questions for 20 minutes and abruptly ended the interview although I did answer most of the questions correctly.

    Initial Phone Screen by Recruiter followed by technical phone screen. Recruiters are good and nice to talk with. Then came the Tech interview. He called me 10 mins later and then started talking all nonsense - we don't have managers here, we work for only 50+ billion dollar companies, all are seniors here & what not. Finally 10 mins he asked some basic java questions which he also not sure when I responded with a question back he continued saying ok lets leave it... Finally it ended & I was relieved.

    Anonymous Interview Candidate in New York, NY
    Application Details

    I applied through a recruiter. The process took a weekinterviewed at Lab49 in March 2014.

    Interview Details

    I was contacted via LinkedIn.

    The recruiter was fairly enthusiastic about the company and largely sold me on the idea of working for them. Then, came the ten or so multiple choice trivia questions that she asked.

    They seemed to be satisfied with my answers, so they scheduled me for a phone interview. However, approximately 5 minutes before the phone interview was scheduled to begin, I received an e-mail stating that they'd need to reschedule.

    Having conducted many technical interviews at my current job, I know that asking trivia questions, even as a gateway to a more advanced technical phone screen is not a good idea since you will get too many false positives and too many false negatives. Not only that, being asked to reschedule, 5 minutes prior to the interview is also very unprofessional and I've never been in the position where I've had to do such a thing to a candidate whenever I've been scheduled to conduct an interview.

    Java Developer Interview

    Anonymous Interview Candidate
    Anonymous Interview Candidate
    Application Details

    I applied through other source. The process took 3 weeksinterviewed at Lab49 in February 2014.

    Interview Details

    The company found my profile in LinkedIn, the vacancy looked interesting so we decided to start the interviewing process. The process itself consist of several parts: at least two technical phone interviews, one Skype interview with a Senior Stuff Member.

    Technical interviews were quite professional: the first one was about OOP, Java Basics(collections, structures), the second one was about Threads, non-blocking algorithms, Design Patterns and how to apply them, we also designed a hierarchy of objects for a given business domain.

    Everything was really promising and enjoyable by me as a Java Developer because until the third interview I hadn't got any weird, odd and unsuitable questions as we do in many cases having interviews around.

    So the third interview was with a Senior Stuff Member, who I didn't get the position of, but after that interview I received a very short answer that they are not going to proceed with my candidacy without any explanation why. All questions were about me become a Java Developer, have I ever heard about other Java-based languages and if I used them, about projects I participated in and which problem I faced there. So it was just a chat between two people.

    I feel frustrating and don't really satisfied with the result because they didn't clarify the purpose of decline.

    I applied through a recruiter. The process took 4+ weeksinterviewed at Lab49 in February 2014.

    Interview Details

    I was contacted by a recruiter from this company who was impressed by my on-line profile. The recruiter strongly praised the company. I decided to give a try. The interview process started with two technical interviews by phone. Almost all questions were about Java Core and Multithreading. They were quite average. I didn't have any problems with them. Then I was given a programming task. That task was intended to check Multithreading skills, which I successfully performed. So far so good. The next interview, which turned out final, was with an inadequate person, who in around 15 mins interrupted me with phrase if I had any questions for them and stopped the interview. After that I got an excuse email that I didn't pass the last interview. So, I very much doubt about the competence of that person who made the decision obviously without regard to my huge technical background and previously successful interviews. In conclusion I want to mention that all this embarrassment took 1 month.
