Preguntas de entrevista para el cargo de Senior Java Developer en FirstRand

There were 2 rounds of tech interview I cleared L1 and got call to schedule L2 Just before an hour they cancelled L2 without any reason and without any information After that they never called back or received call. Pathetic way to hire candidate Will advice to have clear communication with the candidate and if u don't want them to hire then just don't schedule call. Wasted the whole day for interview
