Mindteck Automation Engineer interview questions

I had four rounds with this Company. Only 1 technical and rest 3 as a part of project and salary discussion ending up wasting my money and time to travel till their office. The HR dragged me from January till March and at the end reduced my expected salary 4 lacs less than my last company's CTC, though I was clear on my expected CTC. FALSE negotiations and Very Unprofessional HR.
