The process took 3 weeks.

There were 2 steps. The first was an online assessment (OA) that took around 2-3 hours. There were 4 components:

• A short, fast-paced math quiz (maybe 1 minute) with 10 straightforward questions.
• A longer, take-your-time math and logic quiz.
• An assessment over a new, custom-made language that you had to learn during the assessment.
• 4 coding questions, around the level of LeetCode easy/mediums.

The second round was a superday of 4.5 hours, consisting of:

• 2 talk sessions where they described work at Epic
• 1 pair-coding interview, LeetCode easy
• 1 case study where you had to minimize wait time for an urgent clinic
• Finally, a straightforward 1:1 with an HR representative.

Determine if input String A can be converted to input String B by swapping only adjacent characters and print out the result of each swap at a time.
