Sigma group educational academy with its experience in the field of engineering studies have decided to start coaching for ISRO examination for the recruitment for scientists in Electronics. ISRO recruits for the post of scientist / engineer every year. 35 vacancies are reported this year. ISRO offers the position of Scientist/Engineer `SC’ in the level 10 of pay matrix to the young graduates ( Basic Pay Rs 56100/-). The age limit in appearing this examination is 35 years. Not only the one who have degree in their hand but those final year students also can apply for this examination.
For the post of scientist/ engineer the recruitment procedure is conducted in two stages, written test and interview. Based on the performance in the Written Test, candidates will be short-listed for interview. Written test is only a first level screening. Final selection will be based on the performance of the candidates in the Interview and those who secure minimum 60% marks in the interview will be eligible for consideration for empanelment in the selection panel, in the order of merit. On the basis of previous examination, scoring around fifty percentage of questions will not be a big deal for the one who have studied his/ her B.Tech fairly. But the deciding factor of this examination is scoring the remaining 25-30 percentage of questions that greatly comes from areas like Microprocessor, Electromagnetic theory, Communication, Digital Electronics etc. Most of the students are afraid of this examination because of the need for scoring 75 to 80 questions( each question carries 3 marks). Having an excellent knowledge on all the subjects will help the candidates to cross the finish line.
Sigma group have decided to start the classes for ISRO Scientist/ Engineer on March 2017 , such that can be completed within the announced date of examination. Those who are dedicated and confident about his studies and whose who can foresee himself as a scientist in ISRO can easily achieve this job.
