Norstella Software Development Engineer In Test SDET interview questions

Interview process was bit standard after shortlisting , they had 1st technical round Technical round was scheduled with 9+ years experienced QA Even though my background was not into Java as i have clearly mentioned in Resume and to HR , Panel asked questions only on JAVA and asked to write programs in Java. Program was to find duplicates in string He also asked questions on OOPs java , Locators , Jenkins and everything on resume. Did not receive any feedback from HR nor any rejection email and to which i assume i was rejected. It seems , It is common in HR to ghost candidates
