Interview Preparation Tips
Then after putting my lot of time and efforts when finally it comes to release the offer, then they stop picking up the calls and stop responding and the final excuses which I got from them for not releasing the offer is that their software will not allow them to release any offer which is more that 2 days of joining.
Such a pathetic company who even don't know that atleast if you are not releasing the offer, it's your duty to atleast tell the person that either they are not able to provide the compensation as discussed or they are looking parallelly for someone who can settle in less compensation.
Due to all this I have wasted almost my 3-4 weeks of time expecting that I will receive the offer, and didn't focus on other organisations which was ready to provide slightly lower than this.
Hence it's a total scam which is going here suggesting not to get trapped otherwise you will not only waste your time but also other good opportunities as well.
It's a total boycott for me, expecting the same from your end as well, so that they will understand that playing with someone's job is not a joke.

Coding test is a programming challenge that assesses a developer's coding skills and problem-solving abilities. Coding tests can be used in a variety of situations, such as during the hiring process, as part of a professional certification program, or to assess a developer's current skill level.

How to prepare
To prepare for a coding test, you can practice coding on a whiteboard or blank sheet of paper. You can also get used to writing code without an integrated development environment (IDE) or compiler.
How to take the test

Interview Preparation Tips
First Round – Virtual Interview:
The first round was a virtual interview that lasted around 30 minutes. It was smooth and professional, covering the usual technical and behavioral questions.
Second Round – Face-to-Face Interview:
After successfully passing the first round, I was invited for a second and final face-to-face interview. This round lasted over an hour and covered more in-depth technical topics. I left the interview feeling positive and optimistic about the outcome.
Post-Interview Communication:
A few days later, the HR contacted me to request documents and initiated salary discussions, giving me the impression that things were progressing well. However, this is where the problems began.
Months of Silence and Miscommunication:
After these initial discussions, there was complete silence from their side for nearly two months. No updates, no follow-ups—just radio silence. I reached out multiple times, only to be ignored.
L2 Interview Round – Unexpected and Unprofessional:
Out of the blue, I received a call from HR stating that I needed to go through another "L2" technical round, despite having completed the final round weeks earlier. This round felt redundant, and I was ultimately rejected.
Unprofessional HR Behavior:
Throughout this process, the communication from HR was inconsistent, rude, and highly unprofessional. Their lack of transparency, coupled with the abrupt rejection after months of waiting, made the experience even worse.
I would advise anyone considering interviewing with Wipro to think twice before investing their time. The process was disorganized, communication was poor, and the behavior from the HR team was far from professional. Your time and efforts could be better spent elsewhere.
