Expedia SDE-2 OA — 3 string questions solved in ~40 min

Last week I gave OA for SDE 2 role at Expedia. There were two easy string based questions and one medium hard question on string. I solved all the questions in ~40 mins. What are the chances of getting call from HR ?

Comments:

• The HR contacted me more than a month after I completed the OA.
• Same for me, i got rejection email even after completing all question in around 45 mins.

Note: SDE-2 OA at Expedia was string-heavy; solving everything does not guarantee a callback and HR response can take over a month.
