Hi,
In tcs my joining date is passed still not received onboarding link.
Is it normal there because been 4 days delay still they are not giving any update.
It’s kinda hectic to call every time to recruiter and get back with the same answer like work in process.
Should I even expect the joining date?
Let me know if anyone faced that kind of situation before. Tata Consultancy even onboarding manger is not giving Reply’s to my. Mails

If you’re truly past beginner level then focus on joins. Inner/outer and differences and example queries. Joins are by far the most notoriously asked questions in SQL interviews.

I was asked to write a SQL query on a white board for my interview, be prepared!
What type of SQL knowledge are they expecting? For beyond basic querying, you should look into DW stuff like facts and dimension modeling, SCD types. Kimball Group is a good source for anything DW related.
