There are four rounds of AthenaHealth Interviews:
- Technical Assessment
- Technical Interview
- Managerial Interview
- HR interview
Round 1
In the Technical Assessment, based on pseudo-code output, and few main computer science topics like OS, CN, and OOP concepts were asked. There were 2 coding questions. One was finding the count of triplets whose sum is less than or equal to the given user input. Ex : User input : t=8,d=[1,2,3,4,6] Output is 3 as (1,2,3),(1,2,4),(1,3,4) have their sums less than or equal to t. Another question was a long encoded string where each alphabet is encoded with a number like a is encoded with 1, b is encoded with 2, and so on. If any character occurs two or more consecutively, its count immediately follows the encoded character in parenthesis. Example: String is "aabccc" is encoded as 1(2)23(3). Whoever solved any one coding question completely went to the next Technical Interview.

2. Data structures

3. Coding Questions
- Write a code if input is "A1B2C4" then output should be "ABBCCCC"

4. SQL

Situations were given and asked how will you handle it.
Round 4
