4-20 mA signal has a clear zero point, making it easier to detect faults in the system.
It allows for a wider range of measurement values, as the 0-4 mA range can be used to indicate faults or out-of-range conditions.
4-20 mA signal is less susceptible to noise and interference compared to 0-20 mA signal.

Interview Preparation Tips
Totally three rounds of interview where their first two rounds are technical and third round was behaviour interview . The interview went well and they informed me that the result will be announced after 2 weeks of time.
But even after 1 month , I haven't gotten any feedback from them , but the job application status changed to "No longer under construction" in the company's website .They were not even bother to give feedback to the candidate.
Exxon Mobil Bangalore team requires a lot of improvement in the way they are treating candidates and their interviews are very sub standard and needs lot of improvement .
Most of the interviewers were Ex Reliance industries limited employees who run their Own lobby and denying the opportunities for better candidates due to insecurity....So Exxon Mobil Bangalore is in a pathetic situation.....
