Hi folks,
I am going through interview process in Nielseniq currently for Big data engineer role.
Total Yoe - 3.3 years
Current salary - 15 + 1 Lpa approx.
Joined Sapient only six months back.
Can someone provide your reviews so far about the company, mainly looking for learning, wlb can be compromised a bit.
Also, what should be the general expected salary for the role and tech in NielsenIQ ?

Yes. Several days prep for SQL, several months for real code.

LC all medium problems. Some hard. Should be good.
I LC as many medium problems as I can for at least 2 weeks before the D-Day. Almost always, it pays off. For SQL coding interviews though, spend a weekend playing with LC easy/medium problems and you're golden.
I just took one and prepped for a week by just doing a few SQL interview questions I found online. I also went back to make sure I understand theory behind more complex SQL. Studying will help you feel confident regardless of if you know it or not.
It’s one thing to be able to answer a question or define something it’s a whole other thing to be able to explain the application or why you would use a certain thing vs another. Keep that in mind.
Hacker rank SQL is awesome, I'll consider you as above average in SQL if you've completed all the medium and hard question on it.
