Recent interview experiences for dev role

Interview experience and unfair practices If luck is not in your favour, you might do everything right and still not get selected. Here's my experience so far with a few companies I had bad experience with : #Nielsen - Did not revert back to me for almost a month. When they did, they kept another round of interview as my final round and communicated that I was selected. After taking all the documents, they scheduled yet another round with the director and said it will be the final round. Then again, they reached out to me saying we need to keep another round for formality and would not be technical. To my surprise, it was indeed a technical discussion that I was completely unprepared for. The last communication came from them that they CANNOT match my expectations on the compensation as the last round didn't go well. #UIPath All my interview rounds went really well and in fact in one of the rounds the manager gave me an informal confirmation that I will be hired. But then, HR reached out to me that one of the rounds didn't go well and hence they will need to reschedule it. I was okay with that and prepared really well, but during the interview the interviewer did not ask much of technical questions. It was a design round and he was not even interested in the question or my solution. I had to ask him explicitly if he wants me to go through the solution. As a result, the decision was negative. #Twilio Same story as UIPath #Rakuten The interview process took 1 month. I finished all the rounds and HR communicated that the result was positive and asked to submit the documents. HR ghosted me for a week and then informed me that the last round didn't have a positive feedback and hence can't proceed with my position. When I asked her why it was communicated positively earlier, she simply denied it. #F5 Networks They took all my rounds, including the cultural fitment. The director told me during his discussion that he is looking forward to me joining the team. HR expedited the process to finish all my rounds early as the position was urgent and said she will rollout the offer soon. Then, two weeks passed and no response from them. Later, she informed me that they decided to go against other candidate as he came through some referrals. # HPE It has happened twiced that the HR called saying my profile is shortlisted and was behind me to submit the application so that they can schedule the interview. After submitting the application, I got a rejection mail within a week. #Infracloud I went till the last round. It was taken by a female lead who was extremely unprofessional, and asked questions about the keywords that she knew. If I answered with the correct explanation and theory, she would only see if the keyword matches else reject my answers. These experiences shatters a person's confidence completely. And makes you wonder, even with right skills, amazing interview feedbacks, things can still go wrong and you have no control over it. But I wish the interview processes are fair, and one gets what they struggle for.

Need some clarity--Switching from Networking to AI ?

I'm 21F and completed my BCA in 2024 with specialization in Data Science. Luckily, I landed a job right after graduation - currently working at Accenture. Now here's the catch: during my probation, I was trained in Networking (wasn't really given a choice), and naturally, I got staffed on a Networking project. My current tech stack includes: •Azure Cloud •Palo Alto •ServiceNOW •F5 Load Balancer •Aviatrix Now, despite having a Data Science background, I'm working full-time in Networking. But since I'm pursuing my Master's with an Al/ML specialization, I've been wondering... *How realistic is it to switch from Networking to Al?* I'll be honest: my interest in Al is there, but it's not super deep yet. I'm just curious about the field and its future potential. Since I'm still at the very beginning of my career, I'm completely open to switching my tech stack if it means stepping into a space that has higher demand and less competition over time. I do understand that both Networking and Al are strong fields with solid career paths. But right now, I'm trying to figure out where to focus my energy whether to continue down the Networking route I've started on, or to pivot and start building toward AI ? Would love to hear from folks who've been there at similar crossroads. What would you do in my position?
