Bangalore: Most of us tend to get quite nervous before an interview. We get quite confused as we think what to say before the employer? What to wear? How to react? etc. Before facing the recruiter we generally try to get all the necessary details of the company through research. However, due to the speculated economic slowdown interviews can be a little tougher as it can put more stress on the applicants. It is quite important for job seekers and fresh college pass outs to spend some time to brush- up their knowledge and skills before facing a job interview. You should demonstrate yourself as a smart, intelligent and energetic candidate with a professional appearance in front of the hiring manager. Keep in mind that the tech companies are doing quite well in the present economy. Therefore most candidates today are even more inclined towards ingenious tech start-ups for employment. However, the recruitment processes of the tech companies today imitate the way these companies function. According to Danielle Riggs,of 'Psychology at your career's service' some tech companies have quickly gained prominence for asking some unpredictable, weird questions to the applicants. Search engine giant Google has asked a Vendor Relations Manager candidate "How many people are using Facebook in San Francisco at 2:30 p.m. on a Friday?" Similarly tech giant Hewlett-Packard, has asked a Product Marketing Manager candidate "If Germans were the tallest people in the world, how would you prove it?" An engineering candidate was asked at Qualcomm "Given 20 'destructible' light bulbs (which break at a certain height), and a building with 100 floors, how do you determine the height that the light bulbs break?" Likewise, a strange question was asked at Amazon.com, to a Software Developer candidate that "How would you cure world hunger?" Social networking giant Facebook and IBM were also no less in asking odd questions to the candidates like "Given the numbers 1 to 1000, what is the minimum numbers guesses needed to find a specific number if you are given the hint "higher" or "lower" for each guess you make.? And "How do you weigh an elephant without using a scale?" respectively. By asking such weird questions these companies try to find out how an applicant work through the problem and answers a question than the actual answer. Therefore, as advised by the experts if you are asked such weird questions in a job interview do not sit there silently start applying your presence of mind and come up with an answer, never mind even if your answer is weak as they may still like it as they already know that you do not know the answer to the question asked by them. The worst answer that you can tell them is I don't Know the answer.
