The process is straight forward.
1. HR round
HR is very friendly. In this round, they want to see whether you are a good match to their organisation, position. HR ask typical questions like WHY Delivery Hero ?? etc
Tips : Please read about Delivery Hero and impress them with the company achievements. Also, show them how badly you are willing to join Delivery Hero.
2. Technical round
I had 2nd round with the data scientist manager. In this round, they evaluate how much strong on the big data tech stacks. Since, i mentioned spark, presto, he asked few questions w.r.t it. I didn't get coding questions in this round.
3. Technical round
I am interviewed by an Engineering Manager.
Here, 30 min for tech discussion and remaining 30 min for the coding challenge.
Tech discussion is related to the things I mentioned on my resume. like, Airflow, Spark etc.
Coding question was pretty simple. You are given an array of sorted numbers. Print whether the given number can be derived by summing 2 numbers in an array. (2- sum problem). [array contains repeated numbers]
4. Bar Raiser round
I was very scared about the bar raiser round. Because, here you are interviewed by a random senior guy from a different team. I am matched with a Team Manager. He is super cool person and I like his attitude. Always smiling and cooperative.
Round started with some basic resume questions and followed a coding challenge (easy).
Question :
You are given a sorted array with repeated numbers. [1,1,1,3,3,3,3,3,4,5,6,6,6]
Your task is to return the array by not repeating any number more than twice. And the array count. (In place)
Output : [1,1,3,3,4,5,6,6]
Pros :
1. Interview rounds are pretty simple
2. People are very friendly
Cons :
1. Process is quite slow. In my case, it took around 5 weeks and everytime interview is going to postpone due to the interviewer busy schedule.
Tip is that,
1. Be patience
2. Don't torture HR by asking feedbacks (which I did)
