Wabtec Sr. Software Engineer interview questions

They call you for interview at 8.30am and make you sit idle till 11am. At 11am they start presenting about their company details, why they are recruiting..etc.. Btw Wabtech has acquired GE transaportation and in call letter it will be mentioned as GE transportation, you will not know until you reach interview venue. By 12PM they start interview process and they keep on taking 3 to 4 rounds of interview to reject you final HR round. Just because they cant pay you even 20% more than your current package. Please kindly don't attend the interview here, it is waste of time.. efforts gone wasted.
