Post: Sr Consultant 2 grade M2.
I want to know about the company culture,WLB,job security,bench policy.Also,I am a bit confused.The role offered is for a consultant,but the questions were more oriented toward arch. There were no questions on PySpark.The manager said the work is on ETL migration for Barclays using AWS Glue and Spark,but no related questions.Should I take the offer or continue rounds with EPAM,UST,EY?
There are other offers.
Yash Tech:22LAP(fixed)
Publicis Sapient: 25(fixed)
Quantiphi: 25(quoted from my side,no offer yet)
But the thing is that here the work is unclear. Also there are other company rounds going like EPAM,UST.

Interview Preparation Tips
Interview preparation tips for other job seekers - Never believe Deloitte Company. HR would give promises after finishing the HR round which is the last round in most of the companies. Later, they scheduled another round immediately without informing prior and informed that you got rejected after that round.
The candidate gave a counteroffer letter to HR and HR was fully aware of the joining date in that company. But still, HR made a promise on the phone she would give the offer letter a day or two days after the final round ie, HR. The next day HR called me to go through another round with the director and later said you got rejected. The candidate rejected the counteroffer letter and listened to the words of Deloitte HR's promise. So never believe these HR representatives of Deloitte, they will make you go jobless. Very PATHETIC experience. BEWARE OF SUCH FRAUDSTERS.
