Is it good to ask the interview process and turn- around time to reply from the HR team?

Dear Authors, After completing 4 rounds of interview and finally 5th with Director. I asked an update after 15 days. Reply was interview notes are reviewing and we will get back to you.
Is it good to ask the interview process and turn- around time to reply from the HR team? Or pls share any possible solutions.
Generally organisation expects transparency from the interviewee but it is missing from interviewer.

Dear friend,
Replies to your questions are given below:

Reply: - A sound interview handling practice demands recording observations by way of post-interview notes. If some senior authority is reviewing those notes then it is a sound recruitment practice. Please give them time to review.
Secondly, what if there is a contradiction in the opinion of the interviewers who took your interview at the various levels? The reviewer could seek clarification from both and this could consume time than expected.

Reply: - It would be little presumptuous to ask for the turnaround time for the selection process. Senior authorities are busy in myriad activities. Therefore, matter could get stuck at some level. Therefore, the prudence demands showing patience.

Reply: - The company has shared with you the reason for delay when you asked for the update. They told you that they are reviewing the notes. Therefore, where is the question of not being transparent? They could have told you a overused reply "we will get back to you". However, they have not done that. The company is cannot disclose the details of the person who is reviewing the notes, how is he/she reviewing, whether that person is taking any assistance from any one and so on. Obviously, these are the internal matters of the company.

My question is how much time interviewee should wait for an reply after completing certain crucial rounds of interview.

Dear friend,
There is no hard and fast rule that decides the waiting period between last round of interview and the issue of the offer letter. If you think that the time taken by the company to approach you is unreasonable then you have right to turn down the offer. You can exercise that right!
The second factor that decides the waiting period is availability of job opportunities at hand. If you have offer from some other company then avail it of!
Lastly, your second post deserves some feedback to you. It is not just assertive but borders on authoritativeness. You have approached this forum to seek guidance but the question that you have asked is with the feeling that the members are under your control.
A detailed reply has been given to your first post. To bring clarity, the post was not just divided into three parts, but the reply has been given to each part. In the past reply, some questions have been asked about your background, Nevertheless, instead of giving replies to the questions, you have come up with yet another curt post which shows your gratuitousness. Though you have used cloak of anonymity while raising the posts, seasoned members can very well elicit your psychology!
Thanks,
Dinesh Divekar

Organisations conduct interviews, review results and decide upon the candidate or to do fresh selections as the case may be.
No real hard and fast rule can be prescribed.
It depends on organisational needs.
I know in some cases, offer has been made on the spot itself, subject to verifications.
Candidate needs to wait patiently and hope for the best.
If a company takes longer time to decide it is a matter of internal company working and checks and balances.

Dear sir
My intention is to get expert opinion on this before doing any mistake.
Thank you for your suggestions.
I hv not thought about members are under control but I m sorry if my words expressed in that manner
Thirdly regarding anonymous: this is my first post and after post only I came to know this has been showing anonymous. I make sure from next time to use my name and right way of asking the question

Dear Friend,
The expression of frustration on your part is obvious as an aspirant. There is nothing do with intention rather your querries from the expert those who are not even part to process but they only can tell you the possible reasons. Mr Divekar has beautifully addressed the reasons, causes & problems that naturally happens.
Here I am citing an example which has happened in my case. My interview held in month of June and Offer letter issued within 7 days time( the compnay was ready to pay out 3 months notice period) and asked me join as fast as possible within 1st week of July. I could not do even till end of December rather joined in 1 st day of January. You just imagine what could be the situation with the employer, things are not happening as they need badly.
There is also eventuality, many a times management cancelled the interview even the offer letter issued to candidates.
It is better to wait till you get final call from the employer or you can consider the other option if any.

Dear colleague,
Fifteen days' time after final interview can be regarded as good enough to revert to candidate for the outcome.
At the same time it would be improper to ask for turnaround time as the decision may get
delayed due to variety of reasons.
But agree that there has to be reasonableness and good amount of transparency in communication to the candidate.
