I am teaching Java and J2EE Technologies on week ends. Many of the indian and Foreign students are attending the classes. One Sunday i was free. That day i simply went for TCS interview. Within same day, i had all the rounds and cleared all the rounds. Got good salary package. Then i thought of attending more interviews. Now going join good company out of these 5 companies, and going to attend more interviews.
I used to share my experience with the group. so that it will be encouraging and useful to others.
The Software companies are ready to pay what ever we are demanding. They are expecting Good hands on Programming skills, with Logical thinking, Self-confidence. and with Soft skills.
Even for Freshers also, you guys no need to worry about Job in IT Field. Concentrate on Programming, try to understand and learn it. Once if you are good in Coding, U will get good job. There are many start up companies looking for Freshers who are having good programming knowledge.
After some days i will try to share all the questions which are asked in all these companies.
Feel free to contact me for any help.
