got an email from one employee that they shortlist me for a chat interview a total waste of time she was giving me bundle of copied questions on chat and asking me to write down an essay on that scam company

after initial phone screen interview you will have to spend the whole day speaking to 5-7 people from engineers up to vice president about different aspects of software development and your previous experience, solving several assignments etc. So be prepared to take day off if you are currently employed. Well you will have lunch with some of them. Then next day they may ask you to send them your references. Then you can forget about it because you won't receive any feedback anymore. DO NOT WASTE YOUR TIME GUYS. DO NOT APPLY TO STAT-UP-LIKE-COMPANIES ESPECIALLY FOR POSITIONS MORE THAN 30 DAYS OLD. They do not appreciate your time and you as a professional. They really do not need anybody and can spend years playing with candidates. No respect to you. You' d better stay where you are and prepare for position in full fledged big companies. Before applying for any position just check how many months it exists. Good luck!
