Preguntas de entrevista para el puesto de Lead Software Engineer en Trimble

I attended the walk in interview on Nov 16 . There are three rounds. Two tech and one managerial round. 2nd was tough. But I cleared all three and moved to hr round. Everything was going smooth they even said that they were ok with 90day np at that time. Three weeks I did not get offer. Now they asking for another round and. Saying that it because of 90 days of notice very terrible experience. Getting your hopes high and letting you down. Happened to most of the selected candidate. Now again there is walk in at dec 7 so ask carefully that they are ok with all the criteria.
