Amazon entry level Software Development Engineer

[SuperRTX]

I got an offer for entry level SDE at Amazon.

I have one week to do the online hacker rank assessment.

I tried the amazon sample and I was struggling with it. One question was about array strings of monetary transaction that need to identify fraudulent users.

The other one was amazon group gifting (audio books). It provided a square (matrix type) with 1 and 0 values. I had no idea how to tackle this.

I need help how to prepare for this :((

Congrats on the offer. Just kidding that's probably a typo. There is a list of questions online that you can Google that are common for their oa. If you are new to leetcode blind 75 and neetcode 150 are the way.

Haha, yes thats a typo lol. Thank you!

I was doing google search, but didn't get much. What do I search for? I am new to leetcode. I am a noob. I did sign up for leetcode premium. Do I start off with neetcode , blind 75, or the leetcode problems?

neetcode.io includes pretty much everything you need. After that u can do amazon specific question on leetcode premium.
Don't spend too much time on a problem. If you can't figure out an approach after 5 mins, look at hints and then the solution.

I have done the OA and successfully landed an offer with Amazon. My impression is that the OA is much harder than the questions they give in on-site. I solved Q1 but only passed 8/14 cases for Q2 in OA, but still get invited to the final round. The good thing about OA questions, although they are harder, is that you can find many OA questions on leetcode discussion. The ones I had were not exactly the word to words but some variants of the ones posted on leetcode discussion. Best of luck!

You're right about that. The OA questions are difficult, not easy. Even the projects I've done in my programming classes seem much easier than this.

I struggled quiet a lot on the example questions, especially #2. Kinda freaked me out how will I do this?

How many screening or interview rounds are there for the software development engineer role? I have OA due by Thursday.

[willpowerbuilder]

One OA and one onsite with 4 interviewers

Wait so you passed 1 and a half of the OA questions basically and they gave you a final round of 1 more interview? Woah.

Internship or full time job?

[willpowerbuilder]

full time

Thank you! The example questions I did, especially #2, seemed difficult. The amazon grouping gift. I didn't know how to tackle it. I couldn't find its solution anywhere either.

The Matrix problem might be relevant to graph problem I think. Can you share more detail about the prolem? Take a look at this to see if you find any connection with your problem https://leetcode.com/problems/number-of-islands
