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.

Application Fee:

There will be an Application Fee of ₹ 100/- (Rupees One Hundred Only) for each application. Candidates
may make the payment ‘online’ using Internet Banking/Debit Card or ‘Offline’ by visiting
nearest SBI Branch. Candidates after submitting their application can pay application fee
immediately or any day before the last date for fee payment i.e. 06.10.2017 pm. The last
date for submitting online application is 05.10.2017. Candidates are, however, advised to
make online payment by 05.10.2017 toavoid any unexpected transaction failures/issues.
The process followed for each case is shown below:

All Women
candidates/Scheduled Castes (SC)/ Scheduled Tribes (ST); Ex-serviceman [EX] and
Persons with Disabilities (PWD) candidates are exempted from payment of
Application Fee. However, after registration of application on-line, the candidates have to
down-load and print the personalized registration confirmation form from the ISRO system
which will contain the Name of the candidate, Registration Number, Advertisement No., and
Post code for future reference.

The candidates who are already employed under Central/State Govt/PSU/Autonomous
Bodies have to send a `No Objection Certificate’ from the employer concerned, duly
indicating their Registration Number and Post Code to the Administrative Officer [ICRB],
ISRO Headquarters, Bengaluruwithin seven days of filing the applications on-line by
the candidates and in any case not later than 12.10.2017.

Selection Process:BE/B.Tech or equivalent qualification in first class with an aggregate
minimum of 65% marks or CGPA 6.84/10 (average of all semesters for which results are
available). The qualification prescribed and the benchmark are only the MINIMUM
requirement and fulfilling the same does not automatically make candidates eligible for
Written Test. Based on the academic performance and bio-data, initial screening will be
conducted to short-list candidates for taking-up written test. The written test will be
conducted on 24.12.2017 at twelve venues viz., Ahmedabad, Bengaluru, Bhopal,
Chandigarh, Chennai, Guwahati, Hyderabad, Kolkata, Lucknow, Mumbai, New Delhi
and Thiruvananthapuram. However, the Organization reserves the right to cancel/change
the written test venue and re-allot the candidates to any other test centre. The call letters
for the written test to the short-listed candidates will be sent only by e-mail during
second/third of December 2017. The written test paper consists of 80 objective type
questions carrying equal marks. Based on the performance in the Written Test, candidates
will be short-listed for interview, the schedule and venue of which will be notified. Written
test is only a first level screening and written test score will not be considered for final
selection process. 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.
