VO assistance that is Virtual Onsite online interview real-time assistance, in the interview through the shared audio and shared documents for real-time assistance to the interview question and answer, we have a wealth of experience in interview assistance to help you get the ideal interview Offer. I can assist you in OA, VO, so you do not have to spend a lot of time practicing algorithms, memorizing the eight-legged text, learning the design of the system to enter the Internet I can assist your OA, VO, so that you don't have to spend a lot of time practicing algorithmic problems, memorizing eight-legged essays, learning system design, and enter the Internet.
VO assisted process
During the interview, we record the solutions, answers, and related comments in a shared document; your task is to read these and copy the code exactly into the designated interview document.
- Confirm the interview time with us and debug the equipment with us, debug the equipment without problems, pay half of the deposit.
- Interview assistance includes BQ questions, project resume DIVE, technical eight Code, System Design and all other interview-related content, about the project needs to be sent ahead of time to familiarize us with the project documents.
- While interviewing, we are able to see all the contents of your desktop and write a reminder message to you through another device, with the final effect shown in the figure.
Interview process
We not only provide interview assistance services, but also provide interview on behalf of the interview service, for their own code, computer knowledge is weak students, we provide interview on behalf of the interview service, divided into counterparts and full replacement appearance way.
- Counterpoint Style.
Need to simulate the test with you in advance, playing with, your face synthesized my voice, debugging in advance and will explain the precautions, we have a wealth of practical experience to ensure that the interview will not go wrong. - Full Replacement.
We are full replacement out instead of your interview, you only need to give us resume, personal information can be, we will interview the whole recording, suitable for the interviewer and interview for the position is not the same group, similar to the Amazon SDE interview.
We promise hackerrank Passed all written exams, received full marks VOThe company's main goal is to provide the best possible service to its customers, and to provide the best possible service to its customers in the future.
Real-life interview assistance case sharing
Title: Generating valid bracket combinations
Description: Enter a positive integer nOutputs all the data provided by the n Valid combinations for bracketed compositions.
Example: Input. n = 3
Output. ["((()))", "(()())", "(())()", "()()()"]
Examination point: Backtracking, code clarity, boundary condition handling, time/space complexity analysis.
Optimization issues: (coll.) fail (a student) n How to optimize the algorithm when it is large (e.g. close to 10)?
Candidate Thoughts:
- Memoization: Reducing repetitive calculations using memoized search.
- Dynamic Programming (DP): generates all bracket combinations from the bottom up.
Interviewer Comments: The candidate has a good understanding of Memoization and can avoid repetitive subproblems. Propose iterative approach instead of recursion to optimize stack space overhead.
Meta SDE Interview Share 1 - Subarrays of Minimum Length
Title Description:
Given an array containing positive integers nums and a positive integer target, find the shortest consecutive subarray of the array such that the sum of the numbers in the subarray is greater than or equal to target. Returns 0 if it does not exist.
Solution: sliding window
- Maintain a sliding window with a double pointer.
- Increase the right pointer to expand the window until inside the window and ≥ target.
- Try moving the left pointer to shrink the window and record the minimum length.
Time Complexity: O(n).Space Complexity: O(1)
Follow-up:
- What if the array contains negative numbers?
- What if we want to return this shortest subarray itself?
Meta SDE Interview Share - Vertical Traversal of Binary Trees
Title Description:
Given a binary tree, return the result of its vertical traversal. Each column outputs the node values from top to bottom; the same position is ordered by value in ascending order.
Solution: BFS + hash tables
- The hash table records the node values for each vertical column (the column number is used as the key).
- BFS traversal with column number information attached to each node.
- Sort the output results by column number.
Time Complexity: O(n log n).Space Complexity: O(n)
Follow-up:
- How can I optimize storage if the column number range is large (including negative numbers)?
- If the output is required to maintain the original tree hierarchical order?
concluding remarks
After VO real-time assistance, the candidate successfully passed these interviews. We not only provide support on Code and Algorithm, but also System Design and Technical Eight can help.
