Hi,

I do not agreed with you. Any way, your ideal make me thinking about some thing for my project.

Please try to keep posting. Tks and best regards

The team was under pressure at times but you made them believe that it is more of a challenge as opposed to think of it as a stressful situation. The newly designed data packager was also easier to maintain and extend. The management was impressed with the outcome and rewarded the team with an outstanding achievement award. The performance of the newly developed data packager was further improved by 20% by tuning the database (i.e. partitioning the tables, indexing etc).



This approach is not only useful at interviews, but also helps immensely to write outstanding resumes. For example



Situation: Java code that is hard to maintain and reuse. Changes to one module may break another module.

Action:Refactored the code with OO concepts and design patterns in a test driven manner.

Result:The application becomes easier to maintain, extend, and reuse.

You can now construct the sentence as shown below:

  • Re-architected, refactored, and performance tuned a Websphere and JEE based online insurance application, which previously came down almost daily, became a true 24x7 application.

    Hi everybody,

    I uploaded one file. But It can not display. I used internet explorer 8.0.

    How can I repair? Or some problems happened to IE8?

    I know that brushing up the skills is the required thing. i am not relying on the standard interview questions but i wanted to know the depth of interview question so that i helps in interview. Sometimes it happens when you are asked to write a program for a complex program like some atm machine or chess, the idea might not click immediately in that specified time and you might answer from brain when you the leave interview room....sometimes it happens and it happened with same and this is the reason and i wanted some sample question. Hope this helps in understanding my purpose of the post.

    Some accomplish great results in their career, but fail to communicate that effectively in their resumes (i.e. so called quiet achievers) and interviews, whilst others have accomplished ordinary results, but make an effort to communicate that more effectively to stand out from their competition




    Reflect back on your 4 year experience and list down your accomplishments using SAR (Situation Action Result) statements. Here is an extracted example


    Q Give me an example of a time when you set a goal and were able to achieve it? Give me an example of a time you showed initiatiative and took the lead? Tell me about a difficult decision you made in the last year? Give me an example of a time you motivated others? Tell me about a most complex project you were involved in?

    A :
    Situation: When you were working for the ZCC Software Technology Corporation, the overnight batch process called the �Data Pacakager� was developed for a large fast food chain which has over 100 stores. This overnight batch process is responsible for performing a very database intensive search and compute changes like cost of ingredients, selling price, new menu item etc made in various retail stores and package those changes into XML files and send those XML data to the respective stores where they get uploaded into their point of sale registers to reflect the changes. This batch process had been used for the past two years, but since then the number of stores had increased and so did the size of the data in the database. The batch process, which used to take 6-8 hours to complete, had increased to 14-16 hours, which obviously started to adversely affect the daily operations of these stores. The management assigned you with the task of improving the performance of the batch process to 5-6 hours (i.e. suppose to be an overnight process).

    Action: After having analyzed the existing design and code for the �Data Packager�, you had to take the difficult decision to let the management know that this batch process needed to be re-designed and re-written as opposed to modifying the existing code, since it was poorly designed. It is hard to extend, maintain (i.e. making a change in one place can break the code some where else and so on) and had no object reuse through caching (makes too many unnecessary network trips to the database) etc. The management was not too impressed with this approach and concerned about the time required to rewrite this batch process since the management had promised the retail stores to provide a solution within 8-12 weeks. You took the initiative and used your persuasive skills to convince the management that you would be able to provide a re-designed and re-written solution within the 8-12 weeks with the assistance of 2-3 additional developers and two testers. You were entrusted with the task to rewrite the batch process and you set your goal to complete the task in 8 weeks. You decided to build the software iteratively by building individual vertical slices as opposed to the big bang waterfall approach [Refer subsection �Enterprise � Software development process� in Enterprise � Java section]. You redesigned and wrote the code for a typical use case from end to end (i.e. full vertical slice) within 2 weeks and subsequently carried out functional and integration testing to iron out any unforeseen errors or issues. Once the first iteration is stable, you effectively communicated the architecture to the management and to your fellow developers. Motivated and mentored your fellow developers to build the other iterations, based on the first iteration. At the end of iteration, it was tested by the testers, while the developers moved on to the next iteration.

    Results: After having enthusiastically worked to your plan with hard work, dedication and teamwork, you were able to have the 90% of the functionality completed in 9 weeks and spent the next 3 weeks fixing bugs, tuning performance and coding rest of the functionality. The fully functional data packager was completed in 12 weeks and took only 3-4 hours to package XML data for all the stores. The team was under pressure at times but you made them believe that it is more of a challenge as opposed to think of it as a stressful situation. The newly designed data packager was also easier to maintain and extend. The management was impressed with the outcome and rewarded the team with an outstanding achievement award.

    Getting back to a candidate's thought process during an interview.
    When I interviewed with Lutron Lighting (Coopersburg, PA), they had what they call a "situational role-playing interview".
    You sit at table with two interviewers. The interviewers will assume the role of different people in the company as well as outside vendors, customers, and the general public.
    The situation lasts 1 to 2 hours.
    Here is how it works:
    Interviewer says that he is your boss - and he is going to be at very important meetings all day. He knows its your first day on the job - but has a super major problem. Can you help?
    The problem - they are having problems with the lighting controls at the White House. Find the problem, Find the solution.
    Manager says he will be at meetings all day.
    Bye.
    -----
    Note: Once you say bye to the manager - he is GONE forever. Can't get back to him.
    -----
    So what do you do?
    -- You start a paper trail of contacts.
    -- You start by talking with co-worker in cube next to you. He gives you a secretary phone number.
    -- You call secretary. She gives you another phone number.
    -- You call that number. Operator says it's disconnected.
    -- You call information - AT&T operator says that person does not exist.
    -- You try to talk with buddy in cube next door -- but he is out for lunch.
    -- You call operator at your company (you talked to her before). She says you can try to call guys wife.
    -- You try to call guys wife - but get instructions to call pager.
    -- You call pager - leave phone number. But shit!! it's your first day on job - you don't have a phone number yet. You have a phone - but no number.
    -- You go to buddy's cube next to you - he is still out to lunch - so you grab his phone number.
    -- Leave sticky note on buddy's phone stating you are expecting phone call.
    -- Place page with wife.
    -- She calls back.
    -------
    - Making a long story short. This game/role playing goes on and on -- as you keep encountering problem after problem in trying to track down people.
    - In the meantime, you keep a list of contacts - as you may need to go back to them.
    ----
    - Final solution to problem:
    - Secret Service was waving metal detectors at wall switches for lighting and these caused the circuit boards to die.
    - As the clincher. You had to order replacement parts. Which required a purchase order. Which required you go to the secretary who knew the ropes and could get you an emergency one. This you gave to supplier who delivered the new switches to White House.
    SIMULATION OVER.
    ------
    - That sure beats the hell out of manhole covers.
    - Was a hell of a lot of fun.
    - Interviewer says 3/4 of candidates can't coordinate their thoughts or maintain a paper trail of what they did. Paper trail needed so that you know who to contact in case you have problems and need to find another way around situation.
    -----
    - Lutron Lighting was the only place I ever saw it done.
    - Thing is, this is how the real-world operates. Certainly saw it a lot at EDS - where you had to go through 10-15 folks sometimes in order to get a problem solved.
    Gotta run,
