Hi!, I recently got an offer from Cognizant as a Data Engineer Role.
It consists of three rounds

1. Technical MCQS
2. Coding Round
3. Technical and HR Round

• Questions asked in the first round were of medium level. Questions in this round covered from the topics {OOPS, ERROR DETECTION, FILLING MISSING CODES, SQL}
• Three Questions were asked in Coding Round, where each question consisted of 2 questions.
• First two questions were problem solving one and were of medium level.
• almost all questions were about DP and GREEDY
• The Third Question was SQL related and was a moderate Question as well

I was qualified in the First Round and was Qualified to the second Round. I answered Two questions of Three coding questions, I couldnt attend Third question which was SQL related.
In next few days, I recieved a Mail regarding Second Round qualification.

• Technical Round was little easy for me, because interviewer was very friendly. He asked me basic coding questions and concepts like OOPS and DBMS

Finally, I recieved a mail regarding selecting process.

**TIPS FROM MY EXPERIENCE **

• Dont stop coding, solve as much as you can everyday
• Dont Learn too many concepts at a time
• Stick to one programming language
• Learn by doing, I mean projects
• Dont jump to the answer early, Atleast stick to a problem for an hour
• Read others Code or watch Youtube (This is the most important tip from my experience)
• AGAIN!, practice, practice, practice...

BEST OF LUCK
