Hi everyone,

I have an upcoming interview for the Staff Data Engineer role at Walmart, and the next round is expected to cover Low-Level Design (LLD) for Data Engineering.

However, I haven’t found many threads or discussions online about the specific types of questions asked in this round at Walmart. I would greatly appreciate it if anyone who has gone through a similar interview process (especially at Walmart) could share insights or experiences.

Thanks.

In LLD they could talk about optimisations (storage and query).
What databases you used, what engine you used and all.
Expect questions on Spark too.
And you can always ask what does it mean by LLD? Will it be a coding round too.

Thanks buddy for sharing your thoughts. I tried checking with HR, she did not have much information on exact technical to be che.

It was not related to data-engineering LLD at all though the position was staff data engineer. The interviewer asked me to design a food delivery application's LLD and it's a related question like what design principal I used and why.

How can recruiters be so stupid to interview for data problem but ask to design business application problem.

Let's start from this forum. Attend the LLD round and share the questions here.

Hi Fishes,

l interviewed for Deloitte (India not USI) in January, and accepted an offer letter with DOJ of 25th April, later HR asked me to join on 11th April for which I agreed. Now I haven't received the revised offer letter or any links other than BGV and Pre-Hire form from Deloitte and now the HR is not even picking my calls or responding to emails.

Any advice on what to do?
