Landis+Gyr Sr. Software Engineer interview questions

Interview process is good and the team is friendly in nature. medium difficulty level. they have 3 rounds of interview 1st technical round where they ask me questions about strings, data types bitwise oprations etc. 2nd is managerial round he ask me about modules , link list , approaches about different scenarios. 3ed is HR he ask me about company what does it do n all.

Normal interview process after completing all round even HR , they reject candidates saying they got rejected in technical round. Worst HR management and managerial round. They didnt know what to say to save their own image.
