Preguntas de entrevista para el cargo de Java Software Engineer en Intech Process Automation

I was called by HR executive and ask some basic question related to past technology experience and salary expectations. I was asked to come for first technical interview. I was on time and office location and setup was very pleasent and professional. Then I was technically eveloated in 45 min session. Interviewer was very technically sound person and he told me he was technical operations manager. We started in light mode. He ask me of any difficulty to reaching intech. He than give me technical problem and said we have to solve this together. He asked my many question between solving the problem related to the logic and strategy I used. He asked my alternate approaches. After that I was asked to complete an assignment. Which was a restfull client fetching data from restfull webservice and applying some rules to filter the data. After that data has to save in db. I completed the assignment. But I did not fully completed the unit test. My assignment was rejected due to not up to their standards. I think its due to not 100% unit tests. I skip many unit test due to short time. At the end HR were not responsive. They did not told me that my assignment was not up to the mark. I send them 4 emails to ask status. Eventually they replied.
