Workplace reviews and discussion: 荷蘭商臺灣戴爾股份有限公司台灣分公司

This company is located on Section 2 of Dunhua South Road, opposite Trend Micro.

The position being interviewed for involves using C# to write a desktop app for Windows.

Therefore, C# is a basic requirement. Since Java and C# are quite similar, you can also apply if you know Java.

According to the interview process schedule, you will go through five consecutive interviewers.

The questions were as follows:

Q1: Given a linked list, return a linked list with the head and tail reversed.

In other words, if the original order is A -> B -> C, return C -> B -> A.

This must be done in-place; do not allocate a large amount of memory.

(This should be LeetCode #206: Reverse Linked List - https://leetcode.com/problems/reverse-linked-list/)

Q2: Given two binary trees, tree A and tree B, determine whether tree A could become identical to tree B after swapping nodes. Return true if possible, and false otherwise.

Q2-1: Then they asked about the time complexity.

They asked whether I had ever played the 13-card poker game. I said I had not.

He said this was the only question he used when interviewing other candidates and told me to take it on.

Q3. Given 13 playing cards as input, output a combination of hands arranged as 5, 5, and 3 cards.

Please define the data structures first, then provide your answer.

The possible hand combinations are:

p1. Straight flush

p2. Four of a kind

p3. Flush

p4. Full house

p5. Three pairs

p6. Two pairs

p7. High card

Since this is a whiteboard interview, you may want to practice writing on a whiteboard and make your handwriting look a little neater.
