Just to get a factual perspective, I have some campus placement figures (ref: my RTI query).
# Students enrolled for placement Jun10(1224); Dec10(1119); Jun11(584); Dec11(1659); Jun12(1584); Dec12(1077); Jun13(1106)
# Students placed on Campus Jun10(87); Dec10(104); Jun11(139); Dec11(113); Jun12(71); Dec12(167); Jun13(NA)
# Single largest employer Jun10(Coal Ind); Dec10(BHEL); Jun11(Coal Ind); Dec11(Coal Ind); Jun12(Wipro); Dec12(Wipro); Jun13(NA)
# Students placed with largest employer Jun10(38); Dec10(32); Jun11(110); Dec11(68); Jun12(35); Dec12(41); Jun13(NA)
I am told that EIL, CIL, GAIL, MMTC, NHB, IDBI, IREDA, IRCTC, ONGC, STC, SEBI, NLC, PGI, BEL, Allahabad bank, Exim Bank are the PSUs, and most generally recruit in bulk. There are Corporates as well, many names, but they typically recruit in single digits. Wipro had a special drive in 2012, but I am told it was a spike (and not a fresh trend).
It would be safe to average out the enrollment to 1000-1500, of which only 8-15% seem to be securing placement. Of these about 80%+ are recruited by the PSUs, and 10-25% by the Private Sector. TCS does feature on campus since Dec '11 but not as a bulk recruiter. Obviously, my observations are based on whatever the Institute chose to share under the RTI (to my specific questions). I do not have raw data.
Regards to the Corporate recruitment, as a operating philosophy, Corporates expect the Institutes to certify that the candidates were competent in their 'trade' (Engg / MBA/ CA/ CS/ CMA). So, questions related to 'costing' would largely be to test waters.... and not to probe any deeper. Most Corporate recruiters would rely on 'aptitude test', 'English writing proficiency test' and 'group discussion'. Interviews tend to evaluate your 'personal grooming', 'clarity of thinking', 'extra-curricular-s', 'general awareness', 'financial aptitude' and 'awareness about financial happenings'. Its more about thinking-on-your-feet than 'preparing' for the interview.
So, my suggestion is not to get too anxious. Just be yourself.... and someone-or-else will see your goodness.
Incidentally, your computer literacy will be of great help for being job-worthy. Experience with Oracle, SAP, SQL, MS-Access will improve your employ-ability 5-10 times. If not anything, do a quick course in Tally ERP-9.... wherein you educate yourself with all the ERP-functionality that it offers (and did not provide in earlier versions of Tally).
I suppose, as a result of the sluggish economy, the campus-recruitment from Management schools / Engg colleges, in general have been slow this year. I suspect the same will show in our campus placements as well. So, the competition will be stiff.... and one needs to 'stand out' of the crowd.
Best wishes, again!
