Adobe SDE HackerRank OA Questions You Must Know in 2026

Just finished it recently Adobe SDE OA (HackerRank), to be honest: the repetition rate of the question bank is not low, and the probability of getting the same set is very high. This OA has a total of 3 lines of coding, one of which is fixed in Python. If you are preparing for Adobe, this set must be saved.

OA basic information

  • Platform: HackerRank
  • Number of questions: 3 Coding
  • Language: 1 question requires Python
  • Difficulty: Moderate, but easy to overturn in details

T1 | Minimum absolute difference pair (high frequency)

Question meaning

Give one Array of integers without duplicates, find out All pairs of numbers with the smallest absolute difference:

  • Each number pair is internally sorted in ascending order
  • All pairs of numbers are output in ascending order of the first element.

Core idea (one sentence version)

Sort + scan adjacent

  • After sorting, the smallest difference can only appear in adjacent elements
  • Linear traversal:
    • Smaller difference → clear results, update
    • Same difference → join directly

Rollover point

  • Forgot to clear old results
  • The output order is not handled properly

T2 | Temperature operation reaches the maximum value (easiest to get stuck)

Question meaning

  • Starting temperature X
  • Target temperature Y
  • Most Z Operations (+1 / -1 each)

Require:
What is the maximum temperature that can be reached during the process without finally reaching y?
If you can’t arrive, return directly -1

The key to solving the problem (really just these 3 steps)

① Is it accessible?

  • Z < |x - y| → direct -1

② Parity is the soul

  • Steps and distance Parity must be consistent
  • Inconsistent → actual number of steps available K=z-1
  • Consistent → K=z

③ Rushing strategy

Go straight up first, then turn around and go back to y

The maximum value is calculated directly:

(x + y + K) / 2

There are a lot of people asking this question

  • No, no, yes Didn't expect parity
  • Or the strategy is too complicated

T3|Distinct substrings of length k (specify Python)

Question meaning

Give string Password And integers K,statistics The number of distinct substrings of length k

Flash sale ideas

Python = set Tianxuan

  • Traverse from 0 to N-k
  • Cut a substring of length k each time
  • Throw them all in Set
  • Return Len(set)

Pay attention to the boundaries:Len(password) < k

To sum up the true style of Adobe OA

Let’s be honest:

  • Not difficult, but very easy to fall into a trap
  • No partial questions
  • The focus is on:
    • Basic algorithm understanding
    • Mathematics & Logical Derivation
    • Details + boundary conditions

It’s not that many students can’t write, it’s that they waste time on trial and error.

Why is it easy to fail when answering questions?

Those who have done Adobe OA should understand:

  • HackerRank Time is tight
  • If you think wrong about one point, the whole question will be completely useless.
  • Especially questions like T2 that “seem to be simple, but are actually full of details”

So, many students will choose Programhelp in key OA fields. OA traceless assist :

  • Real-time thinking reminder to avoid going astray at the beginning
  • Timely prompts on key conditions and boundaries to reduce low-level mistakes
  • The entire process does not interfere with the operating rhythm, and is suitable for mainstream platforms such as HackerRank.

Many students are actually capable during the question writing stage, but they make mistakes in the formal OA due to nervousness and disrupted rhythm.
The value of OA Traceless Assistance lies in helping you "reliably do the questions you could have done correctly correctly."

If you are preparing for OA from companies such as Adobe, Google, and Amazon, especially if time is tight and the number of questions is concentrated, this type of assistance can often significantly improve the passing rate.
