BDO Senior Manager interview questions

Following the final interview i did not hear back from BDO for almost 2 weeks at that point HR still did not clarify if I had been successful or not. They said they were still interviewing.Fast forward another two weeks HR emailed and asked when i could speak i responded but they did not acknowledge my email.I did attempt to make contact but at this point knew it was a waste of time.Whist i appreciate comparing candidates can take time i would expect a professional services firm to be able to do so professionally and with consideration and clearly communicate timelines to the candidates. I asked to be removed from the recruitment process as it highlighted that BDO would not be a work environment i would like.
