Hello Nithish,

Every Engineering company looks to hire some fantastic piece of brains, they want to ensure every candidate they hire should be a good. Good at aptitude, Good at Logic, Good at Communication (Differ's between Company to company).

Majorly IT companies can be divided into 3 Categories.

•  M.N.C (Companies having offices all over the globe / Companies strength 10,000 + )
•  M.S.E (Companies may / may not have offices across the globe / Companies strength below 10,000 )
• Start ups ( Companies Just begun, less than 5 years old. Companies strength below 500 )

Each of this above categories have different ways of recruitment. Moreover it also depends if the company is a I.T Services Company or I.T Product Company.

Product companies normally have very high standard of recruitment and services companies (not all) are more concerned about the head count.

Recruitment pattern of most services companies is as follows:
1. Aptitude/ Logical Reasoning Test
2. Group Discussion
3. Technical Interview
4. H.R Interview
Note: Most big companies (M.N.C's have percentage criteria for being eligible to appear for the Interviews)

Hope this helped you.

Thank you.
